WebbAdd any justifications for the effect size above, including any code used to compute the value. If the smallest effect of interest is not based on a simple effect, but on a more complex data pattern, leave the 'value' field empty, and choose 'Other. Specify in the field below' in the 'metric' field. WebbWell, lets say you run a power analysis for a t-test (or for a correlation), and you set the smallest effect size of interest as d = .4 (or the equivalent r-value). If you then run your analysis and find d = .6 and the effect is significant, then your study had enough power to determine this effect.

This is more than current practice. flybe toulonWebbLakens ( 2014) uses the label ‘smallest effect size of interest’ (SESOI) for the smallest effect size that is of interest to a researcher. The proposed method in this paper specifically enables applied researchers to specify such a SESOI – which, in turn, can be used to plan the required sample size for a given experimental test of an intervention. greenhouse kits to buy
