Cohen's d pooled is calculated as follows: Cohen's d = mean 1 - mean 2 weighted SD, with weighted SD = SD1 + SD2 2.
El Cohen's d pooled es calculado de la siguiente forma: Cohen's d = promedio 1 - promedio 2/DE ponderada, siendo DE ponderada = DE1 + DE2/2.
O Cohen's d pooled é calculado da seguinte forma: Cohen's d = média 1 - média 2 / DP ponderado, sendo DP ponderado = DP1 + DP2/2.
