Gene -

A good textbook on psychological testing and measurement will have a chapter(s) on normative data that will include a definition and the characteristics of the data sample.  If you're looking for something quicker, the two links below may help.

Subject: [IPAC-List] developing normative data

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.
