Kenneth,ICC(1)的值是不是应该在0.2左右才说明小组加总是可行的?

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.”/ ?6 N: S p) | `' ]# Z( U" d
