Calculating Effect Size (Cohen

WebEffect size The difference of the means between the lowest group and the highest group over the common standard deviation is a measure of effect size. In the calculation above, we have used 550 and 646 with common standard deviation of 80. This gives effect size of (646-550)/80 = 1.2. This is considered to be a large effect size. WebA One-Way ANOVA that mirrors the independent samples t-test will provide F (1, 18) = 6.34, p = 0.022, and statistical software such as SPSS will provide the effect size η 2 p = 0.26 (which is identical to η 2 G in a between subjects ANOVA).
