Notwithstanding a large body of literature on log-linear models and odds ratios, no general marginal-free index of the association in a contingency table has gained a wide acceptance. Building on a framework developed by L. A. Goodman, we put into light the direct links between odds ratios, the Altham index, the intrinsic association coefficient,…

In this paper, a test based on rank sums is considered specifically for problems where there is a priori indication that the experimental condition may cause extreme reactions in both directions. (Authors)

A distribution-free test for trend in one-way experimental designs is described. Critical values are derived, and a schematic diagram is given so that a computer package can be implemented. (Author/JKS)

The program presented computes a chi-square statistic for testing pattern hypotheses on correlation matrices. The statistic is based on a multivariate generalization of the Fisher r-to-z transformation. This statistic has small sample performance which is superior to an analogous likelihood ratio statistic obtained via the analysis of covariance…

This text is designed for undergraduate courses in statistics or tests and measurements in physical education. It covers basic statistical concepts such as frequency distributions; graphs and curves; percentiles; measure of central tendency and variability; correlations; t tests; special applications of t tests for unequal, small, or correlated…
