Sternberg (1981) presented correlations based on independent samples of about 25 cases each with a statistical comparison in a population parameter of zero and interpreted his results as if with appropriate tests. He needed to use a nonzero population parameter and compare for the difference between the z transformations. (Author/CM)

Sternberg's reply to paper Humphrey criticizes (see TM 507 045) includes: (1) invited position paper and detailed statistical testing would have been inappropriate; (2) Humphrey commits some of "misdeeds" of which he accuses Sternberg; (3) number of cases in the three nonentrenchment experiments are more than adequate for drawing conclusions; and…

Data in Yarworth and Gauthier's article on student self- concept and participation in school activities (EJ 189 606) were reanalyzed by Walsh and Winne (TM 505 375). Yarworth and Gauthier's criticism of the reanalysis (TM 505 376) is answered. (GDC)

Yarworth and Gauthier (EJ 189 606) examined whether self-concept variables enhanced predictions about students' participation in school activities, using unstructured stepwise regression techniques. A reanalysis of their data using hierarchial regression models tested their hypothesis more appropriately, and uncovered multicollinearity and…
