Is the heartrate level of males and females after thirty minutes of exercise significantly different after completing each of the following routines: cardiovascular, weight-lifting, and yoga? Fifteen males and 15 females performed each of the routines, one each day over three consecutive days; the order in which routines were assigned was random. Heartrate was measured after each routine was performed.

B: RM
C: CRF
D: RMF
E: SPF
F: ANCOVA

ANALYSIS OF COVARIANCE
Analysis of covariance is used to test the main and interaction effects of categorical variables on a continuous dependent variable, controlling for the effects of selected other continuous variables, which co-vary with the dependent. The control variables are called the "covariates."
