Question

If performing a repeated measures ANOVA with both a between subjects (e.g., sex) and within subjects (e.g., drug dose) variable, which statistical test should be performed?

a. Independent samples t-test
b. Paired samples t-test
c. Two-way ANOVA
d. One-way ANOVA

Answer 1

The correct statistical test to perform is a two-way ANOVA.

Step-by-step explanation:

If performing a repeated measures ANOVA with both a between subjects (e.g., sex) and within subjects (e.g., drug dose) variable, the correct statistical test to perform is a two-way ANOVA (answer choice c).

A two-way ANOVA is used when there are two independent variables (factors) and one dependent variable. In this scenario, the between subjects variable is sex and the within subjects variable is drug dose. A two-way ANOVA will allow you to analyze the main effects of each variable as well as any interactions between the variables.

By conducting a two-way ANOVA, you can determine whether there are significant differences in the means of the dependent variable across the different levels of the between subjects variable (sex) and the within subjects variable (drug dose).
