Effect sizes should be compared to a reference table. For Cohen's d, this table gives the interpretations of different d values: Effect size d Very small 0.01 Small 0.20 Medium 0.50 Large 0.80 Very large 1.20 Huge 2.0 For example, if d = 0.3, we would say that the effect size is small. A study finds a p-value of 0.5 and a Cohen's d value of 0.06. What is the correct interpretation of the results of this study? O We fail to reject the null hypothesis and find a very small effect size. O We fail to reject the null hypothesis and find a small effect size. O We reject the null hypothesis and find a very small effect size. O We accept the alternative hypothesis, and find a small effect size
