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)

Attempts to determine what effect, if any, a color's hue or value has on the elementary school child's perception of apparent weight. (Author/RK)

Argues that women are unaccounted for in most phenomenographic studies, for several reasons: most research has been conducted in fields and using samples in which women are underrepresented; the traditional disciplines of study are patriarchal; and the "outcome space" is defined in cognitive terms, neglecting the affective dimension…

The article proposes a strategy for the assessment of young children with handicaps in which brief clinical sampling is used to document developmental skills. This information may then be used in designing intervention programs. Principles and techniques of brief clinical sampling are described and application examples are given. (Author/DB)

Single sample approximations are considered for the cross-validation coefficient in the analysis of covariance structures. Results of a random sampling experiment--using data from ability tests administered to high school students (sample sizes 100, 400, and 800)--illustrate the coefficient and adjustment for predictive validity. (SLD)

Description of common errors found in the statistical methodologies of research carried out by librarians, focuses on sampling and generalizability. The discussion covers the need to either adapt library research to the statistical abilities of librarians or to educate librarians in the proper use of statistics. (15 references) (CLB)

Provides a physical description of semivolatile organic compounds (SVOCs), both in terms of their characteristic nature in the atmosphere and the processes which control their deposition. Contains a summary of the requirements for a full assessment of atmospheric SVOCs and their deposition. (LZ)
