Reliability Analysis

Post by kevinlech »

When I try to do reliability analysis, it is does not give mean and sd either for scale statistics and or item statistics. It also throws an error if one items has no variance.

Can you elaborate on that? If you exclude item without variance, do the problems persist?

Items without variance (in other words constants), usually end up in an error as they don't discriminate between subjects and can't be used in creation of scales, measures, etc. Just eliminate them from analysis and work from there...
