    Question

    Below is a portion of an ANOVA table belonging to a CRD ANOVA with 5 groups and 3 measurements per group.

    ————— —- —- —- — — Source of variation df SS MS F P Among groups 4 48 Within groups 10 15 Total 14 63 ————— —- —- —- — —

    Suppose the F-value of this ANOVA table was equal to 3.0; then the following would apply for the corresponding P value to hold (α=5%):


    1. TRUE: P > 0.05: no significant differences between groups
    2. FALSE: P > 0.05: significant differences between groups
    3. FALSE: P < 0.05: no significant differences between groups
    4. FALSE: P > 0.05: do have significant differences between groups.

    1. P > 0.05: no significant differences between groups: Correct
    2. P > 0.05: do have significant differences between groups: Incorrect
    3. P < 0.05: no significant differences between groups: Incorrect
    4. P > 0.05: significant differences between groups: Incorrect
