Hello to everybody on the list.
 
I'm trying to equate two test using a common persons approach. I'm not sure how to handle extreme scores: should I elimanate persons with extreme scores on test A and B from the calibrations and only calculate the equating contants with non-extreme persons?
 
thank you for your comments
 
Andrés
