A table of critical values is presented for use with Chacko's ordered alternatives test for the analysis of variance. (Author/JKS)

Experimenters sometimes wish to estimate for a particular dependent variable the proportion of total group variance that is associated with mean differences among fixed treatments or subject classifications. Hays (1981) represents this proportion by the parameter omega squared. A point estimate may be easily computed as a function of the number of…

The multivariate analysis of variance approach to the analysis of data from repeated measures designs that include covariates is reviewed and contrasted with univariate methods. Assumptions necessary for meaningful interpretation of the results of the multivariate analysis are discussed and contrasted to those of the univariate approaches. An…

As an extension of B. Thompson's 1998 invited address to the American Educational Research Association, this paper cites two additional common faux pas in research methodology and explores some research issues for the future. These two errors in methodology are the use of univariate analyses in the presence of multiple outcome variables (with the…

The Test of Spoken English (TSE) is an internationally administered instrument for assessing nonnative speakers' proficiency in speaking English. The research foundation of the TSE examination described in its manual refers to two sources of variation other than the achievement being measured: interrater reliability and internal consistency.…

In 1991, a study was conducted of Miami-Dade Community College students' classroom experiences. The process involved randomly selecting one section for each full-time faculty member and administering the surveys prior to the final course withdrawal date. Surveys were returned from 640 sections (84% of those initially selected), and responses were…

In an attempt to correlate effective school practices with actual observed student achievement, a survey instrument concerning principal leadership and school climate was distributed to classroom teachers in the Oklahoma City Public Schools. Responses by more than half of the teachers yielded 1,294 usable questionnaires representing all 94 schools…

In 1989, a study was conducted of the academic achievement of Harrisburg (Pennsylvania) Area Community College (HACC) students who transferred to State University I (SUI) during the fall semesters of 1983, 1984, and 1985. A total of 81 students were identified and their academic records were tracked through the end of the spring semester 1989.…

This report presents an account and evaluation of a two-year survey-feedback problem-solving organization development (OD) project in a small city's school district. The project combined the survey-feedback technology with structural alterations in the school district and the training of internal change agents. Both planned and unplanned events…
