This means that if the difference between the means of two groups is less than 0.2 standard deviations, the difference is insignificant, even if statistically important. Pearson’s r michelin exalto

"WebThe Cohen's d statistic is calculated by determining the difference between two mean values and dividing it by the population standard deviation, thus: Effect Size = (M 1 – M 2 ) / SD. SD equals standard deviation. In situations in which there are similar variances, either group's standard deviation may be employed to calculate Cohen's d. " - Cohen's d calculation in minitab
