Four sets of data and the corresponding conclusions found in Haire et al. (1966) were correlated with eight indicators obtained for fourteen countries. (Author)

The use of generalized discriminant analysis as a descriptive technique which can be employed outside of the traditional analysis of variance studies is discussed. Examples based on real data are provided. (Author/JKS)

The triangular decomposition method is suggested as a general technique for obtaining the various measures of an ill-conditioned matrix. The advantages of using triangular decomposition are computing nicety, cost, and parsimony. (Author/PN)

The author suggests that Seymour Sargent's article, "The Uses and Limitations of Trueswell," is a mixture of facts, opinions, and misunderstandings regarding the "Trueswell procedure." He points out several of Sargent's erroneous interpretations and attempts to clarify his research objectives. (JD)

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological…

This article reflects on key methodological issues emerging from children and young people's involvement in data analysis processes. We outline a pragmatic framework illustrating different approaches to engaging children, using two case studies of children's experiences of participating in data analysis. The article highlights methods of…

THIS NOTE OFFERS A MEANS FOR ANALYZING THE DIFFERENCES IN THE LEVELS OF TWO RATIOS OVER A PERIOD OF TIME WHEN THOSE RATIOS COME FROM EMPIRICAL DATA. THE PARTICULAR EXAMPLE USED PERTAINS TO WHITE-NONWHITE PERSONAL INCOME DIFFERENTIALS OVER A TIME INTERVAL, BUT IT IS NOTED THAT THIS TYPE ANALYSIS CAN BE USED IN OTHER CIRCUMSTANCES. (HW)

The greatest fallacy of word counts, the author maintains, lies in the fact that advocates of frequency lists stress the high percentage without telling the whole truth. It has become common to pretend that a frequency list of 3,000 words covers 95 percent of the language, that it enables a person to speak and understand a foreign language by…

Two objectives guided the present study: (1) to provide a suitable test for the hypothesis rho=0, and (2) to establish a means by which general users of R can set confidence intervals on rho. The first objective was approached by testing several possible solutions similar to the procedure followed by Forsyth. The second objective was pursued via a…

Three different nonparametric tests for scale--the Siegel-Tukey (S-T), the Mood (M), and the Normal Scores (NS)--are compared in order to contrast varying methods of scale test development and usage. Procedures for developing the three scale tests are discussed, and two examples of the use of each test in solving the same problem are given. From…
