    The following data were obtained from an independent-measures research study comparing three treatment conditions. Use an ANOVA with ? = 0.05 to determine whether there are any significant mean differences among the treatments.
    Treatment
    I II III
    2 5 7 N = 14
    5 2 3 G = 42
    0 1 6 ?X2 = 182
    1 2 4
    2
    2

    T = 12 T = 10 T = 20
    SS = 14 SS = 9 SS = 10

    Please use a hand calculator and show the calculations for the SSbetween, SSwithin, and SSTotal. Also make a hand-calculated ANOVA summary table with the SS, df, and MS, and state the hypotheses and the critical value.
