Practice: Calculating the t-test for Paired-Samples/Dependent Means (Drugs and Learning)

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), making a decision about the null hypothesis and summarizing the results. An answer key is included.
