The following data are from an independent-measures experiment comparing two treatment conditions. Treatment 1 Treatment 2 4 19 5 11 12 18 10 10 10 12 7 14 A. Do these data indicate a significant difference between the treatments at the .05 level of significance? M1 = _____________________________ SS1 = _____________________________ M2 = _____________________________ SS2 = _____________________________ tcritical = _________________________ sp² = _____________________________ S(M1-M2) = _________________________ tcalculated = _________________________ Decision = ________________________ B. Compute r2 to measure the size of the treatment effect. r2 = ______________________________________________ C. Write a sentence demonstrating how the outcome of the hypothesis test and the measure of effect size would appear in a research report.

A. Do these data indicate a significant difference between the treatments at the .05 level of
significance?
M1 = _____________________________
SS1 = _____________________________
M2 = _____________________________
SS2 = _____________________________
tcritical = _________________________
sp² = _____________________________
S(M1-M2) = _________________________
tcalculated = _________________________
Decision = ________________________
B. Compute r2 to measure the size of the treatment effect.
r2 = ______________________________________________
C. Write a sentence demonstrating how the outcome of the hypothesis test and the measure
of effect size would appear in a research report.
