1: A researcher surveyed two groups of professionals, nurse practitioners and physicians, and asked them whether or not they supported expanding the role of nurse practitioners’ (NPs) prescribing privileges, answered as either “yes” or “no.” Her research question is: Is there a difference between NPs and physicians on proportions of support for expanded prescription privileges? What is the appropriate statistic to address the research question?

Answer: –

2: What statistic would be appropriate for an associational research question involving the correlation between two non-normally distributed, skewed continuous variables?

Answer: –

3: A researcher is interested in the extent to which years of practice among NPs predicts level of support for expanded prescription privileges, measured on a 10-point Likert scale. She finds that both variables, years of practice and level of support, are normally distributed. Her research question is: Does years of practice among NPs predict level of support for expanded prescription privileges? What is the appropriate statistic to address the research question?

Answer: –

4: What statistic would be appropriate for a difference research question involving the comparison of two independent groups on a normally distributed continuous dependent variable?

Answer: –

5: A statistics professor tests her students’ level of knowledge at the beginning of the semester and administers the same test at the end of the semester. She compares the two sets of continuous scores. Her research question is: Is there a difference in statistics knowledge from the beginning to the end of the semester? What is the appropriate statistic to address the research question, if the scores are normally distributed?

Answer: –

6: What is the appropriate statistic to address the research question in Question 5 if the scores are NOT normally distributed?

Answer: –

7: What is the appropriate statistic to identify the association between two dichotomous variables, where the researcher is interested in identifying the odds of an outcome occurring?
