Instructors should assign this problem (about drugs and learning) to students as in-class practice or homework after students have learned how to calculate a t-test for dependent means and test for significance. The activity leads students through determining the type of statistical analysis to use, the hypotheses, calculating the t-ratio and effect size (if appropriate),

The goal of this PowerPoint is to work through the step-by-step process of hand calculating a t-test for dependent means. The slides start with an explanation of the formula involved and then a sample problem is presented. It is designed for you to have the class solve the problem along with you as you advance
