Question

Given the following 3 sets of data (same as before, shown again here): Group 1: (23, 41, 16, 75, 48, 63, 94, 50, 47, 35); Group 2: (24, 36, 39, 83, 52, 37, 64, 5, 30, 12); Group 3: (26, 73, 45, 68, 33, 81, 76, 93, 44, 34)

Say the data came from three different groups of subjects' scores on a math test, after Group 1 was given coffee, Group 2 was given beer, and Group 3 was given a math review sheet. For this question, assume the data violate the assumptions for parametric tests.

Run the appropriate non-parametric test to determine if coffee, beer, and review sheets have significantly different effects on math scores; choose the correct results to report below (Hint: 'Analyze->Nonparametric Tests', see ch. 15).

There was not a significant difference in math scores between groups, H(2) = 2.55, p > .05

There was a significant difference in math scores between groups, H(2) = 2.55, p < .05

There was a significant difference in math scores between groups, W(1) = 4.0 , p < .05

There was not a significant difference in math scores between groups, W(1) = 0.4, p > .05

There was not a significant difference in math scores between groups, H(2) = 2.55, p > .05

There was a significant difference in math scores between groups, H(2) = 2.55, p < .05

There was a significant difference in math scores between groups, W(1) = 4.0 , p < .05

There was not a significant difference in math scores between groups, W(1) = 0.4, p > .05

Explanation / Answer

There was not a significant difference in math scores between groups, H(2)=2.55,p>0.05
