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.

Step 1 State the hypothesis:

Step 2 State the alpha level and reason for selecting it:

Step 3 Indicate which statistic you have selected:

Step 4 Calculate and list your Sum of Squares:

Step 5 Calculate and list your d.f. values:

Step 6 State the rejection rule:

Step 7 Calculate Mean Squares and the F-ratio:

Step 8 Make a decision whether to accept or reject the null hypotheses and state your decision in terms of the problem

Step 9 Post Hoc Test needed or not.
