WebThe standard deviation was 17.69, so Cohen's d becomes: d = -1.81 / 17.69 = 0.10. Cohen suggests to multiply this with the square root of 2, to get a generic d, for which he gives a rule of thumb for the classification as shown in the Table 1 (Cohen, 1988, p. 40). The 0.10 from the example would get multiplied by 2 which gives 0.14. WebCohen's d is the appropriate effect size measure if two groups have similar standard deviations and are of the same size. Glass's delta, which uses only the standard deviation of the control group, is an alternative measure if each group has a different standard deviation.
