Information Retention as a Function of the Number of Intervals and the Reliability of Continuous Variables.

Schiel, Jeffrey L.; Shaw, Dale G.

Applied Measurement in Education, v5 n3 p213-23 1992

Changes in information retention resulting from changes in reliability and number of intervals in scale construction were studied to provide quantitative information to help in decisions about choosing intervals. Information retention reached a maximum when the number of intervals was about 8 or more and reliability was near 1.0. (SLD)
