Estimates of population values obtained using three sampling techniques (simple random sampling, stratified random sampling, and cluster sampling) and three size samples for each technique (10%, 25% and 50%) were compared with known "population" values. 25% simple random sample provided quite good estimates of the "population"…

A sampling methodology is proposed for determining lengths of tests designed to assess the comprehension of written discourse. It is based on Bormuth's transformational analysis, within a domain-referenced framework. Guidelines are provided for computing sample size and selecting sentences to which the transformational rules can be applied.…

Discusses the importance of a knowledge of basic statistical concepts for a librarian's education, and the problem of implementing such an introductory course. Two class exercises dealing with sampling and probability and the Central Limit Theorem are described, and 11 references are included. (BK)

Dunnett's procedure for comparing K-1 treatments with a control is discussed within the context of three nonparametric models: those of Kruskal-Wallis, Friedman, and Cochran. (Author/MH)

An annotated bibliography intended to add to the advancement officer's understanding of the survey (its design, techniques, and uses) is provided. (Author/MLW)

Provides pointers regarding seven basic steps for writing a student body public opinion survey news story: selecting a topic, forming some hypotheses, designing a questionnaire, constructing a sample design, collecting the data, analyzing the data, and writing the news story. (GT)

Tells how staff members of a college newspaper worked out a procedure for obtaining and interviewing a sample of students that accurately represented the entire student body. (GT)

Examines the relationship between survey feedback and the organization environment to determine under what environmental conditions survey feedback was perceived by subordinates as having had an impact and if there is any systematic relationship between the degree of feedback provided to subordinates and the impact of survey feedback as perceived…

Bytheway discusses the problems of representation and sampling methodology found in the Three Generation Family Study directed by Hill at the University of Minnesota. Hill responds to this criticism and challenges Bytheway to provide a better sampling design. (Author/HLM)

The Colorado Treatment Outcome Study, a longitudinal study of people with mental illness, developed an integrated management approach that resulted in average recontact rates of 95% in each followup year. The approach includes multiple facets with an emphasis on partnership of all participants and agencies and respect for the individual. (SLD)

Distinguishes two conceptions of sample and sampling that emerged in the context of a teaching experiment conducted in a high school statistics class. Suggests that the conception of a sample as a quasi- proportional, small-scale version of the population is a powerful one to target for instruction. (Author/KHR)

This article examines methodological issues confronting the study of qualitative and quantitative differences in ways that separated parents share time with their children. Measurement issues explored include disentangling dimensions of contact, identifying economic implications of contact, and measuring quality of contact. Sampling issues relate…

The asymptotic sampling distributions (means and variances) are presented for the signed and unsigned estimates for the Rasch model, two-parameter model, and the three-parameter model with fixed lower asymptotes. Applications for item-bias research are discussed. (SLD)

Describes the use of computer graphics simulations to enhance student understanding of sampling distributions that arise in introductory statistics. Highlights include the distribution of sample proportions, the distribution of the difference of sample means, the distribution of the difference of sample proportions, and the distribution of sample…

Equating two parallel forms of the College Board Biology Achievement Test using three sampling strategies was examined. For each strategy, five equating procedures were studied: Tucker and Levine equally reliable linear equatings; frequency estimation equipercentile equatings; chained equipercentile curvilinear equatings; and three-parameter…
