q3 i? Classifying individual study effect sizes against criteria of 0.00–0.20 low, 0.21–0.50 moderate, 0.51–1.00 high, and above 1.01 very high, the authors obtained eight medium, ten high, and thirteen very high studies. → Ridwan 2021

q3 · i? · quant-synthesis · r1

Forest-plot analysis (Figure 1) of the 31 individual effect sizes using a random-effects model, classified with Cohen et al. (2007) criteria. The authors report "eight research studies with medium effect sizes, ten criteria for high, and 13 others were very high".

"Based on the effect size criteria for values of 0.00-0.20 low, 0.21-0.50 moderate, 0.51-1.00 high, and matters more than 1.01 are very high (Cohen et al. 2007). We obtained eight research studies with medium effect sizes, ten criteria for high, and 13 others were very high."
