Question

The National Collegiate Athletic Association (NCAA) cares about success for athletes both in their sports and in their education. A researcher hired by the NCAA wants to know how athletes' academic performance is affected by the stage of their competitive season. She examines performance in the pre-season, throughout the active competitive season, and post-season, having 150 athletes, from across several different sports, assessed during each period. What statistical analysis would be appropriate for this research?

a. one-way within-groups ANOVA

b. independent-samples t tests

c. one-way between-groups ANOVA

d. paired-samples t tests

Explanation / Answer

c. one-way between-groups ANOVA

since i want to compare mean between 3 or more groups, i apply one way ANOVA to test this hypothesis. When there is a categorical independent variable and a continuous dependent variable and there are more than two levels of the independent variable and/or there is more than one independent variable (a case that would require a multi-way, as opposed to one way ANOVA), then the appropriate analysis one-way between-groups ANOVA
