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. Provides extensive case example of analyses and discusses compensation techniques of weighting and hazard rate models. (Author/NB)

Develops random-effects probit model for case in which outcome of interest is series of correlated binary responses, obtained as product of longitudinal response process where individual is repeatedly classified on binary outcome variable or in multilevel or clustered problems in which individuals within groups are considered to share…

The development of the between-class, within-class analysis has facilitated a more refined analysis of classroom processes and influences: those which affect a class as a whole, a student within a class, or an individual student independent of context. However, a problem arises in using a between-class, within-class analysis to infer a particular…

Evaluations involving nonrandom assignment to treatment or control groups are vulnerable to an accidental or intentional confounding of a selection effect with the treatment effect. Two techniques, discriminant analysis and base expectancy analysis, permit separate estimation of the selection and treatment effects in the final results. (Author/CTM)

Discusses the following aspects of educational evaluation: (1) structural changes; (2) conceptual changes; (3) mixed methods and unraveling consensus; (4) utilization of findings; (5) the role of values; and (6) the role of politics.

Discusses the features of feminist research in psychology. Evaluates proposals for distinctively feminist research methods. Refutes suggestions that experimentation and quantitative research are inherently less feminist than other approaches. Rejects criteria based on sex of participant or researcher.

Reviews several potential problems that often invalidate statistical tests of social theories. Discusses how there may be very serious identification problems in the estimation of the relationship between executions and homicides, and that serious questions may be raised regarding the validity of any particular estimation of this relationship.…

Global figures that reveal the magnitude of the problem of illiteracy in the world disguise great disparities. For example, most of the illiteracy in the world is in developing countries. Therefore, it is preferable, and more appropriate in terms of numerical importance, to concentrate the analysis of illiteracy on developing countries. Such…
