Analysis of Pretest-Posttest Designs.
Schafer, William D.
Measurement and Evaluation in Counseling and Development, v25 n1 p2-4 Apr 1992
Discusses two approaches to data analysis in pretest-posttest research designs in which researcher has not formed groups based on pretest or used pretest information in assigning participants to groups, thus ruling out two-way analysis of variance. Describes use of repeated-measures analysis of variance and two-group analysis of covariance in which the posttest is criterion variable and pretest is covariable. (NB)
