Discovering the Scientist Within offers an utterly unique approach to the research methods course. Rather than taking students through statistical methods one at a time, the authors provide a series of realistic and engaging case studies with each design-focused chapter presenting a single study start to finish.

Online Simulation: Statistical Decision Making

This site has a series of Java animations to illustrate basic statistical concepts related to statistical decision making.

Example activities:
Central Limit Theory: give students a set of distributions to examine at different sample sizes. Have students describe the properties of the central limit theory. Also, they can see if the predicted relationship between the standard deviation of the sample (shown at top) and standard error (shown at bottom) holds.

Statistical Decision Making: Once the figure is explained do simple “experiments” when only knowing the sample and see if the conclusions are correct or not. Show the Ha curve and manipulate effect size and see what that does to the ability to make a “true” conclusion.
