Instruction in mathematical probability to enhance higher levels of critical and creative thinking with gifted students is described. Among thinking skills developed by such an approach are analysis, synthesis, evaluation, fluency, and complexity. (CL)

Brennan's B statistic is a generalized upper-lower discrimination index which was first published in 1972: Peirce earlier introduced a statistic on the relation between a predictor and an outcome which has the same structure as Brennan's B. (Author/CP)

The concept of statistical significance is explained, with specific numerical illustrations. (MNS)

Social scientists have available a wide array of techniques for the analysis of complex contingency tables. Considerations in choosing from among the techniques are discussed. The theme emphasized here is that the analyst should evaluate the techniques within the context of the substantive questions of the study. (Author/JKS)

Uses game theory to help practitioners make decisions about educational games, simulations, or workshops whose outcomes depend to some extent on chance. Highlights include principles for making decisions involving risk; elementary laws of probability; utility theory; and principles for making decisions involving uncertainty. (eight references)…

Provides information concerning a procedure for estimating the probability of placement error on a criterion referenced multiple choice test. (TJ)

This tutorial summarizes some of the widely known limitations of tests of statistical significance and then focuses on extracting measures of variation accounted for as a supplement to significance testing. Two measures of variation accounted for, eta squared and omega squared, are discussed. Computational formulas, computational examples, and…

Provides a protocol for counseling families with an autistic member concerning the risk of having an autistic child. Reports data regarding empirical recurrence risks and identifies the key elements that influence recurrence risks for individual couples. Counseling expertise in both diagnosis and treatment of autism and in the genetics of complex…

Several classroom demonstrations are described that have sparked student involvement in undergraduate courses in probability and statistics. These demonstrations involve experimentation using exams and statistical analysis and adjustment of exam scores. (Author/SLD)

The actuarial profession is described to provide secondary school mathematics teachers insights into how actuaries use mathematics in solving real life problems. Examples are provided involving compound interest, the probability of dying, and inflation with computer modeling. (MDH)
