This article addresses the problem of estimating the proportion Pi[subscript S] of the population belonging to a sensitive group using optional randomized response technique in stratified sampling based on Mangat model that has proportional and Neyman allocation and larger gain in efficiency. Numerically, it is found that the suggested model is…

The Progress in International Reading Literacy Study (PIRLS) is an international assessment of student performance in reading literacy at the fourth grade. PIRLS measures students in the fourth year of formal schooling because this is typically when students' learning transitions from a focus on "learning to read" to a focus on…

School discipline is a core indicator of school effectiveness. Learner management is crucial and educational researchers need to focus on factors leading to indiscipline in schools. Guided by Planned Behaviour Theory that explores on guidance, counseling and good classroom management the study used the survey research design to sample 91 teachers…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

Considered the statistical comparison of groups under the condition of equal sample sizes. (Author)

Paper covers the first part of a study that is concerned with the inferential accuracy of the formulas that have been developed to correct'' several sample statistics for the effects of restriction of range. (Authors)

Many proposed moderators, "explanatory variables," in personnel psychology are probably illusory, having been created solely by belief in the law of small numbers. Race is one such illusory moderator. Also described is a model for validity generalization that questions the traditional doctrine of situational specificity of test…

It is the purpose of this paper to provide social scientists with some insight in dealing with Type 11 error, that is, the probability of failing to reject a false null hypothesis, and therefore, optimum sample size and number of levels, in the random-effects analysis of variance. (Author/RK)

This study presents the results of statistical use in the field of communication as evidenced by the research published in the last two years of the Journal of Communication. (Author/RK)

Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

Investigated empirically through post mortem item-examinee samplings were the relative merits of two alternative procedures for allocating items to subtests in multiple matrix sampling and the feasibility of using the jackknife in approximating standard errors of estimate. (Editor)
