To
a) Two groups of randomly selected students in a medical ethics class were surveyed to compare average hours of sleep per night with class performance. Each group was composed of 14 students.
b) Two 50-patient groups were compared with regard to mean blood pressure before and after a diet intervention. The groups were matched on age, gender, income, education level, race, and history of high blood pressure.
c) Three 100-person groups were compared with regard to post-exercise heart rate. The groups were exposed to light, moderate and strenuous exercise, respectively.
d) Three 100-person groups were compared with regard to post-exercise heart rate and lung function. Again, these groups were exposed to light, moderate and strenuous exercise, respectively.

Explanation / Answer

T-test for 2 non-independent sample means: a) Two groups of randomly selected students in a medical ethics class were surveyed to compare average hours of sleep per night with class performance. Each group was composed of 14 students.

ANOVA:c) Three 100-person groups were compared with regard to post-exercise heart rate. The groups were exposed to light, moderate and strenuous exercise, respectively.

MANOVA: d) Three 100-person groups were compared with regard to post-exercise heart rate and lung function. Again, these groups were exposed to light, moderate and strenuous exercise, respectively.

Here, we need a test that can handle 2 dependent variables, heart rate and lung function. MANOVA can is suitable.

Mann-Whitney: b) Two 50-patient groups were compared with regard to mean blood pressure before and after a diet intervention. The groups were matched on age, gender, income, education level, race, and history of high blood pressure.
