Paired-sample t-tests compare scores on two different variables
but for the same group of cases; independent-sample t-tests compare scores on the same variable
but for two different groups of cases. The links between a subject's pretest and posttest are why the procedure's name refers to paired samples.

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?
