The authors respond to Miley's critique (TM 503 900) of their article on predicting parolee recidivism (TM 502 998). They are pleased that he discovered some computational errors, that he used their method to analyze other data, and that he developed hypotheses concerning the behavior of the parameters.

Discusses collection and analysis of social statistics in developing nations. Concludes that all social statistical programs should stress an approach of integrated and limited improvements related to issues of major concern and aiming to produce timely and reliable information. For journal availability, see SO 506 201. (Author/DB)

Based on a theoretical model of program development, this taxonomy of evaluation relates six evaluation objectives or purposes to nine methodological alternatives. Use of the taxonomy may increase the efficiency of evaluation, improve communication, and assist in the choice of a methodology that is appropriate to the evaluation purposes.…

To date a theoretical basis has not been developed for determining changes in reliability when score points from random guessing are eliminated and those from non-randon guessing are retained. This paper presents a derivation of an expression for the reliability coefficient which displays the effect of deleting score components due to random…

A method for estimating variance-covariance matrices with incomplete data for use in discriminant function analysis is presented. An example of its use in college algebra course placement is also presented. (JKS)

Examines the proposition that metropolitan functional differentiation is related to levels of industrial conflict. Differentiation was measured by specialization of metropolitan areas in particular types of production. Findings indicate that metropolitan functional specialization provides insight into the number of disputes that occur rather than…

A data set from the area of clinical psychology was used to show how multiple regression analysis could be used where analysis of variance might more commonly be used. (JKS)

The evaluators of the Emergency School Aid Act respond to commentaries on their evaluation of the act and their article detailing that evaluation (TM 503 672). Each commentary is discussed. (See TM 503 673 through 678). (JKS)

Recent criticism in the literature of the use of inferential statistics in educational research is refuted. The authors focus on the defense of multiple regression analysis. (JKS)

In this article, two responses to Diane Ravitch's article, "The "White Flight' Controversy," contained in the Spring issue of The Public Interest, are presented. (AM)

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using data from the Clark and Chase sentence-picture verification task, four loci of conflict between these two disciplines are identified: (1) theory versus measurement; (2) meaningfulness versus reliability; (3)…

Questionnaires were distributed to 178 physically disabled persons attending the 1976 Illinois White House Conference on the Handicapped to assess their view of their disabilities. Analysis of responses (eighty-eight, or 52 per cent, completed the questionnaires) indicated general agreement that disability was not a terrible thing, but attitudes…

This paper explains the theoretical links between the demand for library service and key economic variables, and describes how demand was estimated in one specific experimental context: the demand for library service by institutional users of the Cleveland Health Sciences Library. (Author)

Several questions are raised concerning how data is collected and interpreted to generate the National Inventory of Library Needs. The author urges NCLIS to confront some basic issues which have been raised by the document, including data collection techniques and the professional backgrounds of the individuals involved in the study.

Experimental research explores cause and effect relationships. In assessing change, both the degree and direction of change must be determined. Consequently a series of observations must be made over time. The process of change is assumed to be continuous, requiring that observation be as frequent and continuous as possible. (Author)
