q2 · i? · causal · r1

Pre-test Mann-Whitney analysis of both twenty-student groups on the EFL Teaching Methods Test; the total contrast gave Z = 1.328 with Sig. 0.758, and the article reports no significant differences between group mean ranks at baseline.

"Results in Table 3 show that there were no significant differences between the mean ranks of the experimental group and the control group at the beginning of the experiment. This indicates that the two groups were homogeneous at the beginning of the experiment."
