q3 · i? · causal · r2

Writing pre-test administered after five pre-treatment sessions to ensure group homogeneity; the article reports "the proficiency level of the writing ability of the two groups is not significantly different". No effect size is printed.

"The result indicates that the level of significance is more than .05, therefore; the proficiency level of the writing ability of the two groups is not significantly different, t (20.999) =0.703, P= .490."
