Thirty elementary school children in regular, gifted, and learning disabled-gifted programs were examined on three receptive language tests. Analysis of variance indicated that the "Token Test for Children" differentiated learning disabled-gifted, and the "Detroit Tests of Learning Aptitude, Verbal Absurdities Subtest"…

A computer program is described which performs the Bowker test of symmetry in a square contingency table, the Light-Margolin and Pearson tests for homogeneity in nonorder contingency tables, the Kruskal-Wallis test for ordered dependent variables, and the Kandall and Maxwell tests for monotonic trends in ranks.

J. Frass and I. Newman (2000) proposed a hypothesis testing procedure that incorporated the following three key elements: (1) the establishment of a practical significance value; (2) the construction of a non-nil null hypothesis that incorporated the practical significance value; and (3) statistical testing of the non-nil null hypothesis with a…

These papers are on the subjects of playing field standards, surface traction, testing and correlation to actual field experience, and state-of-the-art natural and artificial surfaces. The papers, presented at the Symposium on the Characteristics and Safety of Playing Surfaces (Artificial and Natural) for Field Sports in 1998, cover the…

This paper analyzes three possible research designs using each of the four types of sums of squares in the Statistical Package for the Social Sciences (SPSS). When the design is balanced (i.e., each cell has the same number of observations), all of the SPSS types of sums of squares yield equivalent results (testable hypotheses and sums of squares)…

The tests discussed provide a relatively wide variety of inference techniques which may be applied to "koppa". Each of the techniques may be used to construct confidence intervals, and one specific equation provides a simultaneous test of zero values for two koppas when applied properly. (NE)

One must be extremely careful about reaching decisions concerning the state of a child's cognitive development on the basis of the results of tests that are highly unreliable in their present form. (CK)

Contrary to total time hypotheses it was found that recall is a negatively accelerated function of total presentation time when total presentation time was increased by adding words or slowing the rate of presentation, rather than being a linear function of total presentation time. (AN)
