Research designs that include planned missing data are gaining popularity in applied education research. These methods have traditionally relied on introducing missingness into data collections using the missing completely at random (MCAR) mechanism. This study assesses whether planned missingness can also be implemented when data are instead…

This article reports results of a meta-analysis of survey response rates in published research in counseling and clinical psychology over a 20-year span and describes reported survey administration procedures in those fields. Results of 308 survey administrations showed a weighted average response rate of 49.6%. Among possible moderators, response…

Investigates the question of under what conditions can one infer that some observed relationship between two empirical variables reflects more than that they are both indicants of the same construct. (RC)

Three problems with stepwise research methods are explored. Computer packages may use incorrect degrees of freedom in stepwise computations. In addition, stepwise methods do not identify correctly the best variable set of a given size. A third problem is that stepwise methods tend to capitalize on sampling error. (SLD)

The use of meta-analysis to resolve issues in the fields of organizational behavior and human resources management was reviewed by coding 35 studies on 21 methodological variables. Results illustrate the tremendous variability in how researchers apply meta-analysis. Suggestions are provided for correctly using meta-analysis. (SLD)

In this paper, tables for the appropriate sample sizes are presented and discussed in the context that the determination of the effect size must precede the determination of the sample size. (Author/PN)

This paper reports on the application of Yukl's Management Behavior Survey in 47 elementary schools. Three problems with the instrument are discussed: (1) lack of response; (2) interrater disagreement; and (3) ceiling effects. The dimensionality of the measure is evaluated through factor analysis. (Author/LMO)

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)

An investigation of the Conners' Teacher Rating Scale-Revised hyperactivity scale found that the referents for teacher ratings should be determined, teachers' ratings should be made more objective, standardization across teachers should be demonstrated before norms are preferred, and the rating scale should be validated via observations or other…

This study compares multitrait-multimethod analyses (MTMM) performed on items and factor scores derived from the items. Based upon this demonstration, researchers are encouraged to conduct a preliminary factor analysis before analyzing MTMM data whenever there is a doubt about the underlying trait structure.
