Investigates the merits of individualized instruction vs. traditional methods of instruction. (RK)

Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed for analysis of factor solution. (Author/RK)

First purpose of this study was to investigate empirically the accuracy of prediction using regression weights selected through the use of variance-reduction procedures. (Author)

The present study showed that Rasch-based adaptive tests--when item domains were finite and specifiable--had greater precision in domain score estimation than test forms created by random sampling of items. Results were replicated across four data sources representing a variety of criterion-referenced, domain-based tests varying in length.…

Vocational and technical education researchers need to be aware of the uses and limits of various statistical models. The author reviews the Rasch Model and applies it to results from a nutrition test given to student nurses. (Author)

A survey in Southern California to determine how higher education is responding to the needs of Hispanics is described. The goal was to find out what institutions were doing to recruit Hispanics, retain them until graduation, help them transfer from two-year to four-year institutions, and raise funds. (MLW)

Multiple matrix sampling of items and examinees was applied to an 18-item rank order instrument administered to a randomly assigned group and compared to the ordering and ranking of all items by control subjects. High correlations between ranks suggest the methodology may viably reduce respondent effort on long rank ordering tasks. (Author/CM)

Describes a college class project in geographical survey research comparing the population characteristics in North and South New Jersey. Students made up their own questionnaires and decided on sampling procedures. Surveys revealed facts about population numbers, historical boundaries, employment, and residents' perceptions of regional…

Discusses four ubiquitous major sources of measurement error for individual intelligence scales. Argues that where these sources cannot be directly investigated, they should be estimated rather than ignored. Estimated the typical magnitude of error arising from each of content sampling, time sampling, scoring, and administration. (Author)

Until recently, norms of experimental reasoning have lacked systematic theoretical development. Thus, it has been easy for psychologists like Tversky and Kahneman to misclassify certain human reasoning processes as being Pascalian and invalid, rather than as being Baconian and valid. (CP)

Discusses an instrument developed to assess the counseling needs of older persons. The Older Persons Counseling Needs Survey was administered to (N=107) older persons. Results of a statistical analysis indicated that older persons have a variety of counseling needs that are all approximately at the same need level. (RC)

Reviews factors that determine sample size, recommended sample sizes, recommended procedures for determining the appropriate sample size, and sample sizes reported in published and unpublished evaluations. (Author)
