An analysis is made of the probabilities for winning at the game of Keno, with a computer program provided that will determine expectations. (DT)

Although a great deal of attention has been devoted over a period of years to the estimation of reliability from item statistics, there are still gaps in the mathematical derivation of the Kuder-Richardson results. The main purpose of this paper is to fill some of these gaps, using language consistent with modern probability theory. (Author)

Purpose of the present research was to determine whether certain Pavlovian conditioning phenomena occur in a simple probability learning situation. (Authors)

Applies set theory to the mono- and dihybrid Mendelian genetic crosses, multiple allelism, sex linkage, and linkage to show the application of mathematics to biology teaching (and of biology examples to mathematics instruction). (AL)

Reversals of trait desirability are studied. Terms indicating conservativw behavior appeared to be judged relatively desirable in comparative judgement, while traits indicating dynamic and expansive behavior benefited from absolute judgement. The reversal effect was shown to be a general one, i.e. reversals were not dependent upon the specific…

Higher levels of predicting the more frequent event were achieved with males than females; with the contingent than the noncontingent situation; and with adult males than boys in the noncontingent situation. Females were more likely to repeat an incorrect prediction. (MH)

The problem of whether a precise connection exists between the stochastic processes considered in mathematical learning theory and the Guttman simplex is investigated. The approach used is to derive a set of conditions which a probabilistic model must satisfy in order to generate inter-trial correlations with the perfect simplex property.…

Student access to programmable calculators and computer terminals, coupled with a familiarity with baseball, provides opportunities to enhance their understanding of the binomial distribution and other aspects of analysis. (MP)

Power analysis is in essence a technique for estimating the probability of obtaining a specific minimum observed effect size. Power analysis techniques are applied to research planning problems in test reliability studies. A table for use in research planning and hypothesis testing is presented. (Author)
