given a simple effect size calculation ... some mean difference compared to
some pooled group or group standard deviation ... is it not possible to
obtain the following combinations (assuming some significance test is done)
effect size
small medium large
res NS
res sig
that is ... can we not get both NS or sig results ... when calculated
effect sizes are small, medium, or large?
if that is true ... then what benefit is there to look at significance AT ALL
