Methods of Analysis with Response-Shift Bias.

Bray, James H.; And Others

Educational and Psychological Measurement, v44 n4 p781-804 Win 1984

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)
