Peer reviewedSchneider, Anne L.; Darcy, Robert E. – Evaluation Review, 1984
The normative implications of applying significance tests in evaluation research are examined. The authors conclude that evaluators often make normative decisions, based on the traditional .05 significance level in studies with small samples. Additional reporting of the magnitude of impact, the significance level, and the power of the test is…

Peer reviewedManey, A. C.; Kedem, Benjamin – Evaluation Review, 1982
A novel solution to the statistical problems in an evaluation of rare events is described. The significance of variations in the number of child homicides is analyzed in a binary time series of "active" months for monitoring future incidence and related systemic events. (Author/CM)

Peer reviewedSechrest, Lee; Yeaton, William H. – Evaluation Review, 1982
Methods of assessing effect size and the flows that limit their usefulness are discussed. The various statistical procedures for estimating variance accounted for are based on different statistical models producing sharply differing results. The methods reflect too greatly the particular study characteristics and hence have limited…
