The data below are from an independent-measures experiment comparing three different treatment conditions.
Treatment 1 Treatment 2 Treatment 3
0 1 4
0 4 3 G = 24
0 1 6 ?X2 = 92
2 0 3
T = 2 T = 6 T = 16
SS = 3 SS = 9 SS = 6
Determine whether these data indicate any significant differences among the treatments.
