A nurse researcher studied the effect of biofeedback on blood pressure. For this study, she measured blood pressure on subjects, taught them biofeedback techniques, then re-measured blood pressure on the same group of patients. Which t-test would be most appropriate for this design?

Independent groups t-test

Dependent groups t-test

One-sample t-test

Pearson\'s correlation coefficient

Solution

As the two data are collected from the same patients so the data is no more independent. So we would use a dependent group t-test.

So, option B is correct.
