PICOT:
In hospitalized med/surg patients , does med reconciliation compliance compared to non-compliant medication reconciliation impact 30 day readmission rates?
During Unit 5, you will be working on the following unit outcomes:
· Identify levels of measurement in data collection instruments (CO 2)
· Discuss the implications of levels of measurement for statistical analysis (CO 2)
· Appraise the validity and reliability of data collection methods (CO 4)
· Examine data collection methods in published research studies (C
Here is some more information on variables…
The dependent variable is the variable a researcher is interested in. The changes to the dependent variable are what the researcher is trying to measure with all their fancy techniques. The variable that depends on other factors that are measured.
An independent variable is a variable believed to affect the dependent variable. This is the variable that you, the researcher, will manipulate to see if it makes the dependent variable change. The variable that is stable and unaffected by other variables you are trying to measure. It is the presumed cause.
According to Tappen (2016), the independent variables are defined as the variables that the researcher will manipulate to see if a change occurs in the dependent variables. The independent variable is the presumed cause of change. The dependent variables are what the researcher is attempting to measure.
WEEK 4
Ethical concerns in nursing research often do not have straight forward solutions. Nursing research relies on collaboration and partnerships based on mutual trust. When that trust is breached the damage is irreversible. Honesty, openness, respect and sensitivity to others provide the cornerstones for ethical research. It is important that all nursing research is undertaken from a clear ethical stance, with ethical concerns identified at the outset and reevaluated on an ongoing basis throughout the project.
Take a look at this video about ethical issues and human subjects (9:38)

As nurses, our primary observations are of persons thus we need to think about how to ethically collect data from persons.
The National Research Act of 1974 established three ethical principles for research:
· Respect for persons
· Beneficence
· Justice

Carmen,
· Probability sampling is the gold standard for ensuring generalizability, as it uses some form of random selection in choosing the sample units. The reason that this sample is called a probability sample is each sampling unit has a known chance (probability) that it will be selected (Houser, 2018). Nonprobability sampling does not use random selection so there is no known chance of being selected (Houser, 2018). Nonprobability samples are selected by nonrandom methods. They are often called convenience samples, as the selection is generally based on the convenience of obtaining access to the population. Results from a study where the sample was randomly selected from an accessible population can usually be generalized to the target population far easier than when using a convenience sample.
· Many researchers only have access to a convenience sample so lots of studies report this type of sampling.
