Introduction Senior leadership at Sun Coast has identified several areas for concern that they believe

could be solved using business research methods. The previous director was tasked with

conducting research to help provide information to make decisions about these issues. Although

data were collected, the project was never completed. Senior leadership is interested in seeing the

project through to fruition. The following is the completion of that project, and includes

statement of the problems, literature review, research objectives, research questions and

hypotheses, research methodology, design, and methods, data analysis, findings, and

recommendations.

Statement of Problems Six business problems were identified:

Particulate Matter (PM)

There is a concern that job-site particle pollution is adversely impacting employee health.

Although respirators are required in certain environments, particulate matter (PM) varies in size

depending on the project and job site. PM between 10 and 2.5 microns can float in the air for

minutes to hours (e.g. asbestos, mold spores, pollen, cement dust, fly ash), while PM less than

2.5 microns can float in the air for hours to weeks (e.g. bacteria, viruses, oil smoke, smog, soot).

Due to the smaller size of PM less than 2.5 microns, it is potentially more harmful than PM

between 10 and 2.5 since the conditions are more suitable for inhalation. PM less than 2.5 are

also able to be inhaled into the deeper regions of the lungs, potentially causing more deleterious

health effects. It would be helpful to understand if there is a relationship between PM size and

employee health. PM air quality data have been collected from 103 job sites, which is recorded

in microns. Data are also available for average annual sick days per employee per job-site.

Safety Training Effectiveness

5

Health and Safety training is conducted for each new contract that is awarded to Sun

Coast. Data for training expenditures and lost-time hours were collected from 223 contracts. It

would be valuable to know if training has been successful in reducing lost-time hours and, if so,

how to predict lost-time hours from training expenditures.

Sound-Level Exposure

Sun Coast’s contracts generally involve work in noisy environments due to a variety of

heavy equipment being used for both remediation and the clients’ ongoing operations on the job

sites. Standard earplugs are adequate to protect employee hearing if the decibel levels are less

than 120 decibels (dB). For environments with noise-levels exceeding 120 dB, more advanced

and expensive hearing protection is required, such as earmuffs. Historical data have been

collected from 1,503 contracts for several variables that are believed to contribute to excessive

dB levels. It would be important if these data could be used to predict the dB levels of work

environments before placing employees on-site for future contracts. This would help the safety

department plan for procurement of appropriate ear protection for employees.

New Employee Training

All new Sun Coast employees participate in general health and safety training. The

training program was revamped and implemented six months ago. Upon completion of the

training programs the employees are tested on their knowledge. Test data are available for two

Groups; a) Group A employees who participated in the prior training program, and b) Group B

employees who participated in the revised training program. It is necessary to know if the revised

training program is more effective than the prior training program.

Lead Exposure

6

Employees working on job sites to remediate lead must be monitored. Lead levels in

blood are measured as micrograms of lead per deciliter of blood (μg/dL). A base-line blood test

is taken pre-exposure and post-exposure at the conclusion of the remediation. Data are available

for 49 employees who recently concluded a two-year-long lead remediation project. It is

necessary to determine if blood lead levels have increased.

Return-On-Investment

Sun Coast offers four lines-of-service to their customers, including air monitoring, soil

remediation, water reclamation, and health and safety training. Sun Coast would like to know if

each line of service offers the same return-on-investment. Return-on-investment data are

available for air monitoring, soil remediation, water reclamation, and health and safety training

projects. If return-on-investment is not the same for all lines of service, it would be helpful to

know where differences exist.

Literature Review Health and safety are crucial in managing the risks to protect the employees and the

organization. Researchers attribute workers’ safety environment and culture to managerial

actions and strategies. Given the critical nature of the work environment at Sun Coast, where

employees work in mines to extract toxic substances, safety issues remain core to the

contraction, compensation and long-term litigation. As the safety director at Sun Coast,

evaluation of safety matters narrows us to the following key issues.

Particulate Matter (PM) Article

McClellan (2016) undertook an approach that involved quantitative analysis that on a

microscale exposed a number of sources on particulate matter and showcased a very strong

relationship between the high concentration of PM2.5 and adverse affects it caused. This was

7

validated through a study that was took place between 1970 and 2010, where it showed that the

effects of PM2.5 went down compared to prior years. The crude death rate has also gone down

over time. The death rate in the United States shows that the health effects of PM2.5 are not all

that big when compared to the total number of diseases.

Safety Training Effectiveness Article

Qualitative data from Norris, Spicer, and Byrd (2019) illustrate that the annual 10-hour

safety training courses in the construction sector are inadequate and result in a significant

number of accidents. VR-based safety training helps businesses effectively exercise detecting

and preventing hazards while instructing employees what it’s like to lose without placing them in

risk of losing their lives. Norris, Spicer, and Byrd (2019, p. 37) claimed that the results of this

study “showed that VR training was more effective than traditional training methods in a number

of ways. Researchers found that higher levels of engagement and opportunities for direct, safe

exposure to dangerous environments make it possible for trainees to interact with each other and

get feedback in real time, which enables them learn more.

Sound-Level Exposure Article

Hearing loss is the third most common long-term condition that affects Americans. Most

individuals who lose their hearing do so through recreational activities, which results to hearing

loss complaints in the workplace. Cannady discusses about programs that protect the employees’

hearing and try to keep people from losing their hearing. There are approaches and strategies that

employees and organizations may benefit from having and may include, employees use of

organizational strategies and personal protective control mechanisms to lessen their exposures

during recreation. Controls could include distancing from loud places, reducing exposure time,

8

keeping a safe distance from the source, turning down the volume of the source, or getting rid of

old equipment that causes unnecessary noises.

New Employee Training Article

Per their research, Kostanjek and Jagodi outlined a deployment program established by

the implementer in coordination with the Human Resources functional organization for all new

recruits until they were categorized into their functional units that assisted in their specialized job

profession training. According to Kostanjek and Jagodic (2020), deployment and specialized

training play a key role in accelerating the transfer of knowledge, enhancing the integration of

new employees into the workplace, and contributing considerably to the transfer of information

and skills.

Lead Exposure Article

The study group received 1000 ppm of lead acetate in tap water for 90 days, and revealed

that the frequency of lead exposure was around 21 mg Pb/day per animal. This was intentionally

done to create a model to analyze Pb exchange throughout bodily compartments, namely in bone

tissue. It was concluded that the lead exposure resulted in changing the underlying bone

structure.

Return on Investment Article

In the research conducted by Hoeckel et al. (2019), the authors discuss that everything had an

equal balance when all points are reviewed to understand an supplier-risk’s maturity and

performance. The return on investment is very highly dependent on the risk tolerance level of the

company and his ability to study and decipher the equilibrium between maturity and

performance of the supplier/risk management.

Research Objectives Safety is a crucial component in an organization, especially in areas where harmful

substances are extracted. The government, employees, and the organization executive have a role

in ensuring safety. There are a bunch of perils in today’s workplaces, which, if not taken care of,

will result in employees’ physical injuries and bruises, affecting their ability to report to duty and

the organization’s overall performance. Sun Coast should implement strategies that guarantee the

health and safety of employees at work; if not, they could face serious lawsuits that could lead to

hefty fines or even closure. A lot can be done to reduce employee illnesses and injuries by

conducting a thorough risk assessment, making policies, and implementing the proper

procedures (ComplianceQuest, 2022). Health strategies are crucial in ensuring that both Sun

Coast and the employees understand the potential dangers in the workplace. Training is an

additional component that could be used in Sun Coast to enlighten the employees on the right

procedures, practices, and ways to act to reduce the risk of getting sick, hurt, or contaminated.

Finally, reimbursing for work-related illnesses and injuries affects the company’s bottom line a

lot, which is why it’s essential to have health and safety procedures in place.

However, apart from the company’s management, the government has a role in enforcing

health and safety laws requiring companies to follow specific rules when making their health and

safety procedures (OSHA, 2022). Suppose a company doesn’t ensure its employees have a safe

workplace. In that case, hefty fines should be charged, or even the organization shut down

temporarily or permanently, depending on how terrible the violations are. If the company does

not adhere to the stipulated rules for health and safety, it could lose money, employees, clients,

vendors, productivity, and the company’s brand image.

Research Problem

10

Sun Coast Remediation has lost a significant amount of money in the past due to how

unsafe and dangerous its work environment is. The company’s management has observed that

employees are calling in sick more often, getting hurt or sick more often, and performing less

work. So, it’s important to research how to make and enforce a health and safety policy, as well

as how it impacts the company’s employees and how well they do their jobs.

Research Objective

• To examine the correlation between health and safety at work and also how productive

employees are.

• To figure out what employers can do to improve health and safety at work.

• To find out what employees can do to improve health and safety at work.

• To propose a safety and health policy for Sun Coast Remediation that is complete and

efficient.

Research Questions and Hypotheses RQ1: What is the correlation between health and safety conditions at work and how productive

workers are?

Ho: There exists no statistically significant connection between health and safety conditions at

work (independent) and how productive workers are (dependent).

H1: There is a statistically significant relation between health and safety conditions at work and

how much work people get done.

RQ2: What do employers do to enhance the health and safety of their employees at work?

11

Ho: Employers do not even make a big difference when it comes to enhancing health and safety

at work.

H1: Employers have a significant role to play in improving health and safety at work.

RQ3: What do staff do to improve health and safety at work?

Ho: Employees don’t make a big difference when it comes to improving health and safety at

work.

H1: Employees have a significant role to play in making the workplace more secure and

healthier.

Research Methodology, Design, and Methods

Sun Coast has a number of issues that must be fixed, ranging from These include

particulate matter, how well safety training is done, exposure to noise, training for new

employees, exposure to lead, and ROI. To address these issues properly, it’s important to use

good research methods and assess the issues at stake to safeguard the health and safety of the

employees and the organization as a whole.

Research Methodology

In this investigation, quantitative methods will be used to do the research. Quantitative

methods operate well when the documents are in the form of numbers, which allows to quantify

the correlation between variables so that data can be evaluated (Creswell & Creswell, 2018).

Quantitative research is the most appropriate method to compare Sun Coast because it gives

more social and process-based data that won’t alter the findings for Sun Coast.

12

Research Design

The type of research employed is descriptive research, which does not incorporate

experiments. It will help researchers reach to end state by applying statistical analysis to test

formal hypothesis, thus by exposing the information. This research plan will help Sun Coast

take care of the issues.

Research Methods

Sun Coast will employ three different kinds of research to examine the data that is

collected for this study: descriptive statistics, causal-comparative research, and correlational

research. Considerations about the quantity of lead in the blood are examined using descriptive

statistics. Blood is tested using descriptive statistical techniques to determine how working in

places with lead affects people. The results are based on data and numbers. Correlation methods

are used to discover how the different factors in particulate matter and return on investment are

related to each other. The correlational research method is employed to describe and measure

how closely two or more variables or sets of scores are related to each other. Causal-

comparative research is used to research things like levels of noise, how well safety training

works, and how to train new employees.

Data Collection Methods

The data in this study is retrieved came from questionnaires administered, methods of

observation, and the documentation analysis. This technique also saves money since the

research is done in the same area. The observation methods used to quantify the variables can’t

be garnered from the employees at work. That’s why it’s important, because the researcher gets

first-hand information from the observation method.

13

Sampling Design

Simple random and convenience sampling is an general principle applied in sampling

design. The actual results of an experiment will be generated from random samples, which

cannot be changed. This will be done to make sure that there are no biases and that the sampling

method would get the right number of samples. The data will be collected through observation,

which will be used as the sampling method. Convenience samples seem to be used in places

where employees have been subjected and need to be examined, so the sample cannot be selected

at random.

Data Analysis Procedures

RQ1 attempts to find out if there is a strong correlation between the particulate matter and the

health conditions of employees. Correlation is the best method for evaluating the RQ1

hypotheses because I need to know if there is a relationship.

RQ2 attempts to find out if there is a strong link between the sum of money spent on safety

training and the number of hours lost due to accidents. Regression is the best way to test the RQ2

hypotheses since what matters is whether or not there a relationship. Regression will show if the

health and safety training cut down on lost-time hours and if we can predict lost-time hours

based on how much we spent on training.

RQ3 attempts to find out if we can use noise level to figure out what kind of ear protection is

best. Regression is the best way to test the RQ3 hypotheses because I need to know if there is a

relationship. Regression will demonstrate if there is a link between the use of earplugs, the

amount of noise, and hearing loss.

RQ4 is used to find out if the different training program has worked better than the old one. The t

test is the best way to find out if there is a statistically significant difference between Group A

14

and Group B employees.

RQ5 is used to identify out if lead exposure changed the amount of lead in the blood

significantly. The t test will show whether the new training program is better than the old one.

The t test is the best way to test the RQ5 hypotheses because I need to know if there is a

statistical difference between how employees were before and after they were exposed to lead.

The t test will show if the exposure caused the employees’ blood lead levels to rise.

RQ6 is used to discover out if the four lines of service all have the same average return on

investment. Since more than one line of service is of interest, ANOVA is the best way to test the

RQ6 hypothesis.

Measurement Scale

The measurements of scale used here include interval scale for the Microns and nominal for the

mean sick days of the employees. The two variable are continuous.

Measure of Central Tendency

Mean, mode and median were used to measure the central tendency. The mean, mode, and median

of the microns are 5.66, 8, and 6 respectively. The mean, mode, and median of the mean sick days

are 7.1262, 7, and 7 respectively. The median, mean, and mode are used to determine whether data

has a normal distributions.

Skewness and Kurtosis

The kurtosis and skewness of the microns are -0.8522 and -0.3733 respectively. The kurtosis and

skewness for the mean sick days per annum are 0.1249 and 0.1422 respectively. Skewness should

range from -3 to 3 while kurtosis should range from -10 to 10. The skewness of microns does not

fall within the acceptable range while that of the employee’s mean annual sick days fall within the

acceptable ranges. The kurtosis for both variables fall within the acceptable range.

Evaluation

From the descriptive statistics, the values for the different central tendency measures including

median, mean, and mode were significantly different indicating that the microns data is not

normally distributed. The values of central tendency measures for the employee’s mean annual

sick days were approximately equal which shows that its normally distributed. The skewness of

microns does not fall within the acceptable range while both the kurtosis and skewness of the

17

employee’s mean annual sick days fall within the acceptable ranges. From the descriptive

statistics, it is clear that data on microns is not normally distributed while the data on the mean

sick days for an employee is normally distributed.

The assumptions for correlation were not met.

Pearson correlation coefficient f r = -0.71598 shows that there exists a strong positive

relationship between microns and the average number of sick days an employee takes each

year. This gives us a r2 of 0.5126, which means that we can explain 51.26% of the

31

differences between the two variables. Using a level of significance of 0.05, the results show

that the p-value is 0.000 0.05. So, there are enough reasons to say that the alternative

hypothesis is more likely than the null hypothesis. There is a statistically significant link

between microns and the average number of sick days an employee takes each year.

The Pearson coefficient of correlation, which is equal to the multiple r, is 0.939. This

demonstrated that the correlation between a set of variables is very strong. This gives an r-

squared of 0.8828, which means that the regression model can explain 88.28% of the changes in

the dependent variables (Draper & Smith, 2014). Using an alpha of 0.05, the ANOVA F value is

1664.21 and the p-value is 0.000 0.05. This is strong evidence that the null hypothesis should be

thrown out. So, the slope of regression is a long way from being equal to zero. The equation for

regression is Y = -0.1434X + 273.449. Because of this, the cost of safety training goes down by

0.1434 units for every hour of lost time. The level of significance for the p-value of the

regression coefficient is 7.7E-105 0.05. The regression coefficient is statistically important

because of this.

Multiple Regression: Hypothesis Testing

Ho: There exists no statistically significant connection between health and safety conditions at

work (independent) and how productive workers are (dependent).

H1: There is a statistically significant relation between health and safety conditions at work and

how much work people get done.

Dependent Samples (Paired Samples) t Test: Hypothesis Testing

The data provided for analysis consists of mg/dL pre-exposure and g/dL post-exposure

values for an employee of a certain organization. Our primary problem is to determine whether

the means of the two linked samples are equal. The hypothesis employed is as follows:

H05: Whenever the two associated means are equal, H0: 1 = 2 holds.

Ha5: H1: 1 > 2 if the two associated means are not identical.

Given the hypothesis is a two-tailed hypothesis, we use two-tailed results.

The t-statistic = -1.93

Compared t-statics to t-critical with two tails = -2,011.

Since t (48) = -1,930 > t-critical = -2,011; reject H0 and infer that the means of the two linked

groups (Pre-Exposure mg/dL and Post-Exposure g/dL) are not equal or are different.

ANOVA: Hypothesis Testing

Water, air, training data, and soil are included in the investment return project’s data analysis.

The examination of equality between the two samples will be detected. The tested hypothesis

was as follows: (a=0.05)

HO6: μ1 = μ2 = μ3 = μ4

Ha6: The means are not the same

The F-statistics is 11,923, whereas F-critical is 2,7249.

Since F-statistics = 11.923 > F-critical = 2.7249, reject H0 and infer that the means for air, soil,

water, and training ROI (%) are not all equal.

Findings Students should discuss the findings in the context of Sun Coast’s problems and the

associated research objectives and questions. Restate each research objective and discuss them in

the context of your hypothesis testing results. The following are some things to consider. What

answers did the analysis provide to your research questions? What do those answers tell you?

What are the implications of those answers? Use the following subheadings to include all

required information. Delete instructions highlighted in yellow before submitting this

assignment.

Example:

RO1: Determine if a person’s height is related to weight.

The results of the statistical testing showed that a person’s height is related to their

weight. It is a relatively strong and positive relationship between height and weight. We would,

therefore, expect to see in our population taller people having a greater weight relative to those

of shorter people. This determination suggests restrictions on industrial equipment should be

stated in maximum pounds allowed rather than maximum number of people allowed.

A privately owned island off the coast of Florida has been left to you by the eccentric owner who recently died

Instructions A privately owned island off the coast of Florida has been left to you by the eccentric owner who recently died. The island is large enough for several small communities to be developed. Create a name for your island. You want to start on the right foot by establishing a local government, a judicial system, law enforcement system, and other services typically provided by local and state governments. When setting up a local government, please limit your selection to those styles found in the United States, and avoid dictator, monarchy, or communist systems. For the Unit VII Project, describe the following points:

  • the type of local government you would establish (e.g., county, city);
  • the form of that government (e.g., township, municipal charter);
  • the management system (e.g., commission, mayor, council);
  • how leadership positions would be instated (e.g., appointment, election);
  • the type of law enforcement and judicial system (how judges are selected) you would put into place; and
  • other services typically provided for by local and state governments. Be sure to explain the role of bureaucracies in these services, including how taxes support these services and how those taxes will be collected.

You can mix and match your government, judicial, and law enforcement decisions, but you must fully explain the reasons why you chose the types of systems. You must also address how your government would work with other governments/agencies and in what ways. You can pull concepts from previous readings in this course (not just those assigned in this unit) in order to develop this project. The video tutorial Library Research: An Overview will help you research various aspects of this project. Your project must be at least three full pages in length, not counting the title page and references page. Remember to have an introduction and conclusion to your paper. Library and outside sources are a requirement, and you must use at least three resources to support ideas in your analysis. Avoid conversational tone, and remember that this is an academic assignment, so you must use proper APA Style, grammar, and punctuation

U.S. Coast Guard (USCG) 6003 came back from an afternoon training flight with a dreaded automatic flight control system (AFCS) discrepancy

DISCUSSION ASSIGNMENT INSTRUCTIONS

The student will reply to the threads and the replies must be at least 250 words each. Each reply must incorporate at least one scholarly citation(s) in APA format. Any sources cited must have been published within the last five years. Acceptable sources include the most current sources you can find which likely means the Internet. Make sure to cite all facts in text.

Thread 1 

This week we learned about different approaches to resolving a discrepancy when the general 7-step process just isn’t working out. Regardless of which technique one uses for troubleshooting they must first remember defining the problem, gathering information, and performing analysis still take place when using these other methods (Mostia, 2006, p.74). Now lets take a look at the discrepancy.

One afternoon, U.S. Coast Guard (USCG) 6003 came back from an afternoon training flight with a dreaded automatic flight control system (AFCS) discrepancy. In a certain flight regime on this particular helicopter (approach to hover) there would be an intermittent AFCS degraded caution on the Multifunction display (MFD).

The 6003 is an MH-60T helicopter, manufactured by Sikorsky and the AFCS is a very complex system, designed to assist the pilot in maneuvering and handling the helicopter, as well as many other functions. The system is composed of three major subsystem: stability augmentation system (SAS), the stabilator system, and the digital automatic flight control system (DAFCS) (U.S. G.P.O., 2012, p.121). Each subsystem operates independently of the other two subsystems but as a total system, each subsystem complements the others. The MH-60T flight manual states, “The SAS subsystem provides rate damping and short-term dynamic stability in the pitch, roll, yaw, and vertical control axes” (2012, p.131) The stabilator subsystem optimizes trim attitudes for cruise, climb, and autorotation and provides pitch stability augmentation to complement the SAS system for additional redundancy (U.S. G.P.O., 2012, p.129). The DAFCS provides short term dampening (dynamic stability) and maintains desired altitude, speed, and heading (static stability) (U.S. G.P.O., 2012, p.121).The AFCS is made up of multiple control panels, automatic flight control computer (AFCC), trim servos, boost servos, primary servos, stabilator actuators, amplifiers, sensors, potentiometers, and the list goes on and on. To help with narrowing down component issues, the AFCC generates ground bite and flight bite codes to assist in the troubleshooting. While I would love to go into every specific components purpose, we do not have enough time to completely digest the information. I will attach all associated schematics and information to help assist in this particular discrepancy.

As my team and I dove into the discrepancy, we wrote down the associated flight bite codes, and performed a ground bite to get those codes. From there we went into the maintenance manual to which led us to the computer saying we had a bad collective trim servo. So we replaced that and sent the helicopter on its test flight, in which it came back failing the approach to hover check with an intermittent AFCS degraded. This is were I need you, my fellow classmates to help me solve this repeat offender. Thank you in advance for the help.

Thread 2 

In this week’s course reading we learned a few new methods to approach troubleshooting. For every trouble shooting situation there can be multiple methos used, it all depends on the mechanic and the type of situation found. I personally like the complex to simple method because it is easy to use and most of the time will help you quickly fine the problem. The textbook describes this system as “Involves finding the simple parts that function to make the whole. Once you find the simplest non-functioning “part,” you can evaluate the non-functioning part or, if necessary, you can start at a simple known good part and “rebuild” the system until you can find the problem”. (Mostia, 2006) As a mechanic when approaching a write up we must think what is the simplest component that may be causing this issue. In most cases the simple fix is relatively cheaper that other parts of the system. We as mechanics must complete our work in a timely manner but with respect to completing the task with safety as the number one priority. The book Aviation Maintenance Management define the word reliability as “The probability that an item will perform a required function, under specified conditions without failure, for a specified amount of time according to its intended design”.(Harry, 2013) When we work on specific components we must make sure that they are reliable to the customer.

For my write up I am going to be using a Mooney M20 with an engine issue as an example. The pilot stated that “The engine was running rough”. To the mechanic this could mean a numerous number of things could be wrong. The pilot could have bad fuel, a dead sparkplug, magnetos of time, and the list goes on. To narrow it down the mechanic take the aircraft out or an operational run. Upon the operational check being completed by the repair station they find the engine to be running completely normal. The lead mechanic gives the pilot a call to receive more information. The pilot then adds “I was coming in on my finial approach when I lost oil pressure, then my engine stuttered for a little bit. Once I was laned the engine stopped running rough”. However, when the mechanic was running the engine the oil pressure was normal. Now the mechanic can see that there is something wrong with the oil system.

The way this oil system works is quite simple. There is an oil pan that holds the excess oil in the bottom of the engine. When the aircraft starts it turns a sump which picks up oil and distributes it throughout the engine for cooling and lubricating purposes. However, this aircraft is equipped with a propeller governor. The oil is also pumped into the accessory case to lubricate the gears that are turning the magnetos, alternator, and more.  These types of aircraft use the oil from the sump to control the propeller angle of attack. All the oil once used seeps back to the oil pan to be used again

Data Analysis: Descriptive Statistics and Assumption Testing

            Statistics involves the process of collection, analysis, interpretation, presentation, and data organization in a way that can be understood by its users. Statistical analyses are divided into two broad categories: the inferential and descriptive statistics (Verma & Abdel-Salam, 2019). Descriptive statistics consists of the methods of data representation that calculates descriptive figures and summary graphs or both. The Sun Coast Remediation data was analyzed and presented using descriptive statistics with the interpretations to ascertain whether parametric statistical procedures were met.

Correlation: Descriptive Statistics and Assumption Testing

            The analysis of Sun Coast Remediation data yielded the following statistical descriptive figures and summary graphs.

Measurement scale

            The frequency distribution tables provide a means of ascertaining the measurement scales in which the data was measured.  An analysis of the variables used in data (sick days) revealed that the measurement scale used is ratio scale. Argyrols (2011) points out that a ratio scale uses units that measure equal distance between values on the scale with unique zero.  The variables used indicate sick days with an interval of 1 and with a unique zero as a starting point since there can be zero sick days.

Measure of central tendency

The measures of central tendency are a summary statistic that provides center point of a data set (Argyrous, 2011). The measures of central tendency used in the descriptive statistics for Sun Coast Remediation data are mean, mode, and media. These measures provide the mid-point in which the sick days are dispersed and this can be deduced from the histogram as the mid-point from which the data sets are dispersed.

Evaluation

            The assumptions for parametric assumptions can be ascertained if it were met by checking the histogram curve and the centrality of the distribution of the data. First, the measures of central tendency must be same. In the descriptive statistics, the mean, mode, and median are all same (7). Secondly, observing the histogram shows that the data is evenly distributed with no outliers. Lastly, the observed values for skewness and kurtosis are 0.142249784 and 0.124922603, which are all closer to zero. The general assumption is that the closer the values of skewness and kurtosis to zero, parametric statistical testing can be evaluated using such data. Therefore, the descriptive statistics above met the requirements of parametric assumptions.

Measurement scale

The data set in the variables are ordered with meaningful intervals between the data values without unique zero, meaning it used an interval measurement scale. The measures of lost time cannot have zero starting point, since one cannot say that there is zero lost time.

Using relevant theories and models explored in this unit, write an essay in which you first explain why the phenomenon of ‘overtourism’ (also referred to as ‘anti-tourism’) has emerged to become a significant issue for certain tourism destinations in recent years, and, second, suggest ways by which relevant tourism stakeholder organisations (at global, national and local levels) could help to address this issue.
Overtourism or anti-tourism refers to an organised ‘social protest movement’ that emerges due to increasingly hostile reactions by local citizens towards tourists and tourism development and activity (see https://theconversation.com/overtourism-a-growing-global-problem-100029). It has been particularly obvious over the past few years in popular destinations such as Barcelona, Venice, Amsterdam, Berlin and other significant tourist destinations. There are also indications that at other destinations such as Bali and Byron Bay, local residents are becoming less tolerant of tourists and the impacts that they bring. Of course, there are many, perhaps the greater majority of destinations, where tourism continues to be regarded as an important and largely positive component of the local economy and community. Nevertheless, it is important that the issue of overtourism/anti-tourism is examined critically and its root causes understood, if tourism and its impacts, are to be managed effectively and fairly.
Because overtourism/anti-tourism is a new phenomenon, there is not much academic literature specifically on the topic, although it is growing. There are some non-academic sources such as newspaper and industry/trade magazines that carry articles or opinion pieces on the topic which can be used to provide you with context. But essentially, this essay requires you to use some of the models and theories covered in this unit and apply them to understanding and explaining this problem of overtourism and identify ways that various stakeholder organisations can address this issue. You will need to use the relevant literature to develop your ideas and arguments.
