Describe a survey, instrument, or tool that you plan to use in your project. Describe the tool in terms of name, number of items, how it is answered (Likert scale, yes/no, open answers, etc.), and the total score. Describe the level of measurement for this instrument. Support with references.
Describe the validity and reliability of the instrument you chose in Topic 3 DQ 1. How is this different from external and internal validity?
Describe a vulnerable population in terms of research. Why is the population considered vulnerable? What other groups might also be considered vulnerable populations
Assume you want to do a project that compares the survey results before an intervention to those after an intervention in the same sample (the same people will take both surveys).
You plan to use a paired t-test to analyze your results. Using the “Determining the Appropriate Sample Size,” Topic Material, perform a sample size calculation to determine how large your sample should be. Justify your sample size calculation with citations. Discuss how your sample size may affect the validity of your study.
What are the assumptions for a t-test? How should these be run? Do you want to see a p value of <0.05? Why or why not?
Review the types of data that are considered protected health information (PHI). Do you plan to collect any of this data during your project? How would the collection of this data affect your project (whether you plan to collect it or not)?
Compare your DPI project manuscript thus far to the “Revised Standards for Quality Improvement Reporting Excellence: SQUIRE 2.0” guidelines. Discuss what you can improve in your DPI project manuscript.
