WebFeb 8, 2024 · Cohen suggested that d = 0.2 be considered a “small” effect size, 0.5 represents a “medium” effect size and 0.8 a “large” effect size. This means that if the difference between two groups” means is less than 0.2 standard deviations, the difference is negligible, even if it is statistically significant. Pearson r correlation WebMEMORE recalculates the outcome by taking a difference score of likability_C1 - likability_C2 at various levels of the moderator. The effect is thus the value of the difference score for a certain moderator value. MEMORE then calculates a t-statistic to check significance. I got this output, with a mean-centered moderator:
