Criteria | Experimental group mean, N = 37 | Control group mean, N = 36 | Mann-Whitney U test result |
|---|---|---|---|
Describe observations without explanations | M = 1.97, SD = 0.644 | M = 1.77, SD = 0.637 | U = 562.00, p = 0.195 |
Devise an explanation for an observed pattern | M = 1.62, SD = 0.758 | M = 0.83, SD = 0.845 | U = 342.50, p = 0.000 |
