Focuses on meta-analysis in educational research. Contends that, if significant meta-analysis results are overrepresented through selective sampling, hucksterism in form of sampling bias exists. Explains use of follow-up test, the fail-safe N. Includes tables constructed to assist researchers and practitioners to estimate, without calculation,…

Identifies conditions under which equivalence is likely attained with simple random sampling and randomization in psychotherapy efficacy studies of kind examined in recent meta-analyses. Views consequences of nonequivalence as manifestations of Simpson's paradox. Expects misinterpretations of estimates of relative efficacy of treatments. Compares…

The restrictions on item difficulties that must be met when binomial models are applied to domain-referenced testing are examined. Both a deterministic and a stochastic conception of item responses are discussed with respect to difficulty and Guttman-type items. (Author/BH)

Notes that family researchers can examine extent of self-selection bias in samples by using range of "plausibly correlated characteristics" such as marriage and divorce public records.
