q2 · i? · causal · r2

Tukey multiple comparisons of posttest means following the One-Way ANOVA on gain scores in the quasi-experimental study (30 students per group). Mean differences of .52 (control vs news) and .45 (control vs movie) were significant at .00; the experimental-group contrast (.06) was not significant (Sig. .74).

"there is a significant difference at the level of 0.05 between the Control and Experimental (News) and Experimental (Movie). The results also show that there is no difference between the Experimental groups."
