Design, Analysis and Reporting Considerations When ANCOVA-type Techniques are Used in Evaluation Settings.
DiCostanzo, James L.; Eichelberger, R. Tony
Educational researchers often utilize analysis of covariance type techniques to assess the effects of innovative programs implemented in naturalistic settings. This paper delineates and describes analysis and reporting considerations for the application of analysis of covariance type techniques in public school settings, based primarily on a review and critique of the national Follow Through evaluation. The areas discussed include: relating specific research hypotheses, the results of the corresponding analysis of covariance data analyses and the general evaluation questions; defining the variables; measures of the variables and relationships among the variables; determining whether a covariate is to be included in the analysis; and describing in detail the different groups included in the analyses. Numerous suggestions are provided to assist the reader of reports using analysis of covariance techniques to assess the appropriateness of the technique applied, examine possible alternative interpretations of results, and place the author's conclusions in a more accurate perspective.
