Question

Suppose you are the manager of a mental health agency. You are required to give quality control reports on providing suicide prevention training to your staff. You have invited a national expert on this topic and provided training to your staff. Now you have given surveys on the knowledge of this topic before and after the training to your staff. You collected the surveys back and you are about to conduct statistical analysis to see whether the training was successful in enhancing the knowledge base among your staff.

Group of answer choices

independent sample t-test

One sample t-test

paired sample t-test

Answer 1

Answer: Paired sample t-test

>> The paired sample t-test or dependent sample t-test is a statistical procedure used to determine whether there is a difference between two sets of observations. As each subject or entity here is measured twice (before and after), resulting in pairs of observations, this is a paired sample t-test.
