11. In statistics, an "'effect size "'is a quantitative measure of the strength of a phenomenon. 12. What would the effect size ( based on ( de ) stabilisation energy ) be? 13. For each type of effect size , a larger absolute value always indicates a stronger effect. 14. Deficits in effortful control also showed a very modest effect size in the male direction. 15. For comparison, an effect size of 1.0 would be roughly equivalent to a full letter grade. 16. Wampold found this effect size to be invalid because of the internal biases of the study. 17. This means that for a given effect size , the significance level increases with the sample size. 18. Effect size is one type of practical significance.19. Other fields have favored the estimation of parameters ( e . g ., effect size ). 20. It emphasizes the practical importance of the effect size instead of the statistical significance of individual studies.
