对于ICC(1):
$ D2 v6 ]" k; U6 J; C6 M- Q“We encourage researchers to adopt traditional conventions used when interpreting effect sizes (i.e., percentage of variance explained). Specifically, a value of .01 might be considered a ‘small’ effect, a value of .10 might be considered a ‘medium’ effect, and a value of .25 might be considered a ‘large’ effect“

So in most instances, ICC(K) and ICC(A,K) values >.90 are likely unnecessary. However, depending on the quality of the measures being used in multilevel analysis, researchers will probably want to choose between .70 and .85 to justify aggregation.”
