q2 i? Mann-Whitney U comparison of grade 3 posttest ranks significantly favored the experimental group (p < 0.05). → Amiripour 2017

Amiripour 2017¶

Amiripour, P., Dossey, J.A., & Shahvarani, A. (2017). Using a new schema approach with primary at-risk students in word problem solving. REDIMAT, 6(3), 228-255. http://dx.doi.org/10.17583/redimat.2017.2612

q2 · i? · causal · r2

Nonparametric Mann-Whitney U test on grade 3 posttests (control n = 30, experimental n = 35), used because the grade 3 experimental posttest data were not normally distributed. Mean ranks were 16.60 (control) versus 47.06 (experimental); no effect size is printed.

"The results of the Mann-Whitney U-test showed that comparison of the ranks for the two grades 3 samples (Table 6) to be statistically significant favoring the experimental group ( p asymptotically equivalent to 0.000) in Table 7."
