Discusses three types of faults which commonly occur in statistical sampling. (JG)

Estimates are given for the extent of the overlap of the monograph holdings of the Los Angeles and Berkeley campuses with the holdings of other southern and northern campuses. Estimates of the historic usage rates of the overlapped portions of the collections are also given. (Author/PF)

Treats the problem of testing an ordered hypothesis based on the ranks of the data. Statistical procedures for the randomized block design with more than one observation per cell are derived. Multiple comparisions and estimation procedures are included. (Author/RC)

The sample of monographic literature used in this study conforms to Bradford's law and demonstrates that the law is not confined by political or economic boundaries. (Author)

The procedures involve a planned data gathering strategy consisting of at least two different groups, each receiving two different test batteries. A combination of Tucker's interbattery technique and congruence measures was the recommended strategy. Limitations of the concept of factor invariance are briefly discussed. (Author/BJG)

Develops and illustrates a method for clustering hierarchically the interrelationships between many persons, as represented in a matrix of a thousand by a thousand. (RC)

The National Assessment of Educational Progress; Second Science Assessment No-Show Study assessed the magnitude and causation of nonresponse biases. A No-Show is defined as an individual who was selected as a sample respondent but failed to be present for regular assessment of the 17-year-old group. The procedure whereby a sample of eligible…

The purposes of this study are: (1) to demonstrate the superiority of simple ridge regression over ordinary least squares regression through theoretical argument and empirical example; (2) to modify ridge regression through use of the variance normalization criterion; and (3) to demonstrate the superiority of simple ridge regression based on the…

This study is an a priori demonstration of the applicability of multiple matrix sampling techniques to the practical research problem of parameter estimation. Three tests were administered to two separate but parallel populations, with one receiving item samples and the other receiving full tests. Special efforts were made to minimize the context…

The advantages of Goodman's Gamma, a measure of association, are discussed in reference to the Pearson coefficient of contingency. Both theoretical and practical advantages and disadvantages are discussed. An empirical comparison of the two measures shows that gamma detects significant relationships which chi square does not, and that gamma is…

A general guide to organizing and conducting reliable and useful community surveys is reported. Organization for the survey involves identifying and contacting relevant community groups, and meeting with organizational representatives. Constructing a questionnaire involves careful wording and ordering of questions, and determining if questions…

Pace's College and University Environment Scales (CUES) fails to consider the interdependency of the individual and his environment. A random sample of students (A) and two samples of general psychology students (B) and (C) were used to determine the legitimacy of CUES claims of freedom from: (1) sampling bias, and (2) correlation with individual…

The relationship of sample size to number of variables in the use of factor analysis has been treated by many investigators. In attempting to explore what the minimum sample size should be, none of these investigators pointed out the constraints imposed on the dimensionality of the variables by using a sample size smaller than the number of…

The power of the t, expected normal scores, Mann-Whitney U, Tukey, a modified Mann-Whitney U, and an adaptive procedure were investigated when sampling from population models empirically developed from test score distributions. The models used were selected members of the beta family. This investigation was unique in that not only did the means of…
