A researcher used an analysis of variance to compare three treatment conditions with
a separate sample of n = 8 participants in each treatment. The results of the analysis are shown
in the following summary. Fill in all missing values in the table. (Hint: Start with the df
values.)

Source SS df MS
Between Treatments ____ ____ ____ F = 4
Within Treatments 63 ____ ____
Total ____ ____


So,the DF is 2, 7 and total is 9 am I correct? Don't know how to get the rest?

    Here is how to finish your table:

    To calculate df between:
    k - 1 = 3 - 1 = 2
    Note: k = number of levels.
    
    To calculate df within:
    N - k = 24 - 3 = 21
    Note: N = total number of values in all levels.

    df total = df between + df within = 23

    To calculate MS between:
    SS between/df between = MS between
    Therefore: x/2 = 12; x = 24 (SS between)

    To calculate MS within:
    SS within/df within = 63/21 = 3

    To calculate F-ratio:
    MS between/MS within = F-ratio
    Therefore: x/3 = 4; x = 12 (MS between)

    SS total = SS between + SS within = 87

    Double check my calculations.
