Spss cohen's d
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. Web16 Apr 2024 · SPSS cannot calculate Cohen's f or d directly, but they may be obtained from partial Eta-squared.
