    Question

    A researcher ran a one-way ANOVA (one factor) with 5 groups. The F-test of the ANOVA with the 5 groups is significant at a significance level of 0.05. The researcher then wants to see which of the groups differ from each other. To do so, she wants to correct for multiple comparison with Bonferroni. She must then divide her significance level divided by the total number of tests, or 0.05/k. In this setup


    1. FALSE: K = 5.
    2. TRUE: K = 10.
    3. FALSE: K = 15.

    1. K = 5.: Incorrect
    2. K = 10.: Correct
    3. K = 15.: Incorrect
