Hunter is interested in the effects of exercise on memory for simple and complex spatial layouts (e.g., maps). He hypothesized that people who engage in cardio exercise will remember more complex spatial layouts than people who engage in strength training exercise. He randomly assigned participants to do one of the two exercises, and then had all participants study and get tested on both simple and complex spatial layouts.

Which parametric test should he run on his data?

A. Repeated Measures ANOVA

B. ANOVA

C. Paired samples t-test

D. Independent samples t-test
