An influential statistics test recommends a Levene text for homogeneity of variance. A recent note suggests that Levene's test is upwardly biased for small samples. Another report shows inflated Alpha estimates and low power. Neither study utilized more than two sample sizes. This Monte Carlo study involved sampling from a normal population for…

A study examined the feasibility of developing a cost effective sampling technique which would estimate the mean number of patrons using the Purdue University General Library during one semester. The technique employed, called random sampling without replacement, meant that, from the total population of days in the Fall Semester, particular days…

Examines the reliability and validity of the scores of diverse informants from the Child's Report of Parental Behavior Inventory (CRPBI). Also considers the utility of aggregating scores of parental behavior derived from multiple observers. CRPBI items were adapted to obtain mother's, father's, sibling's, and subject's ratings of parental behavior…

The effects of sample size, number of variables, and population value of the congruence coefficient on the sampling distribution of the congruence coefficient were examined. Sample data were generated on the basis of the common factor model, and principal axes factor analyses were performed. (Author/LMO)

This article considers various kinds of probability and non-probability samples in both experimental and survey studies. Throughout, how a sample is chosen is stressed. Size alone is not the determining consideration in sample selection. Good samples do not occur by accident; they are the result of a careful design. (Author/JAZ)

Tested the hypothesis that increasing library services would increase returns of a questionnaire generated by that library. Students and faculty were surveyed before and after new services were offered at Wharton School. Results suggest source of sponsorship should be related to user group to be surveyed to maximize return rate. (CDD)

A survey of speech communication departments and a review of the literature indicate that most speech communication researchers continue to use college students as their primary source of subjects. The problem of sampling is discussed and methods for dealing with generality are offered. (PD)

Responding to doubts about the validity of test results that showed the Pittsburgh School District's school improvement project to be highly successful, the district validated its results by administering a different test to a representative sample of students in secure conditions. (MCG)

This investigation examined the effect contextual variables had on a national sample of school board members' information needs for decision making. Importance, conflict, and content were found to be associated with board members' needs for time, information, and consultation. (Author/LMO)
