General Review Material

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: Measuring Relationships

This site has a series of Java animations to illustrate basic statistical concepts related to measuring relationships. The illustrations relate to measures that seek to describe if a relationship exists between two variables.

Example activities:
Visualizing Correlations: have students see if they can predict the actual correlation.

Restriction of Range: Change the correlation to different values and see if the effects of restriction of range are the same or different for weak vs. strong correlations.
