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…

Research articles published in 10 major journals during the years 1984-1987 were evaluated to determine how many satisfied the recommendations of the Council for Learning Disabilities' Research Committee on reporting subject data. Only 4 of the 277 articles included acceptable information in 7 recommended areas of subject data. (Author/JDD)

Presents data collection activities for the home, school, and community that encourage students to summarize, interpret, and draw inferences. Four types of activities are discussed: observations, surveys, experiments, and sampling. (Author/MKR)

Provides an introduction to sampling, determination of sample size, and selection of the actual sample that would be useful for librarians conducting research and evaluation studies. Highlights include sampling method, sampling error, confidence level, and microcomputer software packages that help determine sample size. (Contains 26 references.)…

A focal-animal sampling technique was applied to measure and quantify visitor behavior at an enclosed hummingbird aviary. The amount of time visitors stayed within the aviary and how they allocated time was measured. Results can be used by exhibit designers to create and modify museum exhibits. (LZ)

Discusses how to use attribute sampling to assess the accuracy of a library circulation system. Describes the nature of sampling, sampling risk, and nonsampling error. Presents nine steps for using attribute sampling to determine the maximum percentage of incorrect records in a circulation system. (AEF)

Communication samples were collected from 15 normally developing children (ages 11-27 months) during the prelinguistic, single-word, and multiword stages, using both structured and unstructured contexts. Significantly more requests were used during the structured context, but no significant difference was found between the numbers of comments used…
