[IPAC-List] developing normative data

[Gene Carmean]

Hello List:

Does anyone have a definitive definition of normative data?  I have 
found articles describing their characteristics as

1. Scores should come from  a randomly selected population.
2. Scores should be fairly recent since they can change over time.
3. Scores should be derived from a group similar to the one you are 
using as a comparison group, i.e., fitness scores of 12th graders are 
of little use when comparing them to NFL linebackers.

Are there any sources or other key points about norms I should know 
about?  I found this citation, but have no access to ETS articles.

Angoff, William H. Scales, norms, and equivalent scores. Educational 
testing service, 1984.

If anyone can assist with a source or other characteristics I would 
appreciate it.
