The paired sample t-test is used to determine whether the mean difference between two sets of observations is zero. In a paired sample t-test, each subject or entity is measured twice, resulting in pairs of observations (i.e., pretest and posttest in this case).

Dear Dr. Mel, may I know more about the nature of CSO service in HK? I wonder who will help offenders to reintegrate into the community.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
