A New Look at Treatment Differences

Generalized Regression Models in Educational Research
Peer reviewed Peer reviewed
Walberg, Herbert J. – American Educational Research Journal, 1971
Similarities between regression analysis and analysis of variance are noted and it is argued that the former has advantages over the latter. It is also argued that canonical correlation analysis is more suitable than factor analysis in certain cases. The argument is illustrated with four recent pieces of educational research. (DG)

Do Catholic High Schools Improve Minority Student Achievement?
Peer reviewed Peer reviewed
Keith, Timothy Z.; Page, Ellis B. – American Educational Research Journal, 1985
High School and Beyond data set and path analytic techniques were used to compare Black and Hispanic high school seniors' achievement in public and in Catholic schools. When better ability measures were added to the causal models the apparent effect of Catholic schooling on minority achievement was greatly reduced. (Author/BS)
