Let us say there are two Rasch analysis of different data.  One has a very tight participant standard deviation around the mean and the other has a one that is about 5 times as large.  Both have the same item distribution.

Could one infer any of the following:

We would expect sampling effects to be smaller in the first case than the second.

We would say the most of the variability in the data was due to the items in the first case but not in the second.

Comments?
