Question

An educational psychologist studies the effect of frequent testing on retention of class material. The students are randomly assigned to one of two sections of an introductory course. In one section of an introductory course, students are given quizzes each week. A second section of the same course receives only two tests during the semester. At the end of the semester, both sections receive the same final exam. Please choose the statistical test that is most appropriate for this research.

a)Repeated Measures t-test

b)Two-way ANOVA

c)Pearson r Correlation Coefficient

d)Independent Samples t-test

Answer #1

**Answer:** d)
Independent Samples t-test

**Explanation:** The
students are randomly assigned to one of two sections of an
introductory course. That means the two samples are independent. At
the end of the semester, both sections receive the same final exam.
The educational psychologist will compare their final exam score by
using Independent Samples t-test to know the effect of frequent
testing on retention of class material. Hence the appropriate
statistical test for this research is Independent Samples
t-test.
