Question 1

You want to determine the effect of exercise on body weight and measure body weights in 20 subjects before and after a 12 month exercise intervention. Assuming a parametric statistical test, analyzing these data would best be done using:

Group of answer choices

Independent samples T test

Paired T test

One-way ANOVA

Factorial ANOVA

Question 2

You want to determine the effect of diet and exercise on body weight and measure body weights in 20 subjects (per treatment combination) after 12 months of treatment. Subjects are assigned to a diet/exercise treatment combination, so with two diets and two exercise treatments, there are 4 total groups. Assuming a parametric statistical test, analyzing these data would best be done using:

Group of answer choices

Independent samples T test

Paired T test

One-way ANOVA

Factorial ANOVA

Question 3

You perform an experiment where body weight is measured in men and women who are either trained or sedentary, and analyze your data using a factorial ANOVA. You find the following: sex p=0.023; training status p=0.035; sex training status p<0.001. You interpret this as:

Group of answer choices

A significant main effect of sex; no significant main effect of training status; a significant interaction

A significant main effect of sex; a significant main effect of training status; a significant interaction

No significant main effect of sex; A significant main effect of training status; no significant interaction

No significant main effect of sex; no significant main effect of training status; no significant interaction
