1. Campus administrators want to evaluate the effectiveness of a new study skills program. Students who participate in the program are given a survey that asks about their current study skills (the survey responses are numerical). Approximately 6 months after completing the study skills program, participants are contacted and asked to complete the same survey. Administrators want to test whether students study skills improved after participation in the program. Which analytical procedure should they use?

A DEPENDENT T-TEST.

Explanation:

The dependent t-test (also called the paired t-test or paired-samples t-test) compares the means of two related groups to determine whether there is a statistically significant difference between these means.

A dependent t-test is an example of a "repeated-measures" statistical test. This indicates that the same participants are tested more than once. Thus, in the dependent t-test, "related groups" indicates that the same participants are present in both groups.

In this case, the campus administrators want to evaluate the effectiveness of a new study skills program, so students who participated were given survey that asks about their current study skills. After six months, the participants were given the same survey, since the purpose of the survey is to test whether students study skills improved after participation in the program, then THE DEPENDENT T-TEST can be used because there is two related groups.

The first related groups at the beginning of the program and the second related groups after six months can be compared to test whether there is improvement or not.

Therefore, the analytical procedure the campus administrators should use is A DEPENDENT T-TEST.
