q2 · i3 · causal · r2

Quasi-experimental two-group pre-test/post-test study of 57 grade-10 students; the experimental group received eight process-approach writing lessons over sixteen weeks. The article reports a significant within-group change with "d = .83".

"there is a significant change (F (1, 26) = 123.72, p = .00, d = .83) in participants' writing performance in the experimental condition: their post level (M post = 7.66) is higher than their initial level (M pre = 5.78)"

q2 · i? · causal · r2

One-way ANOVA comparing the two conditions after the study found the experimental group significantly ahead; the article prints the F statistic but no effect size for this between-group contrast.

"The post level of participants' writing performance in the experimental condition is significantly higher than that in the control condition (F (1, 55) = 29.62 , p = 00)."
