BASIC programs for computation of the Goodman-Kruskal gamma coefficient

Abstract

In this article, I provide programs in the BASIC language for computing the Goodman-Kruskal gamma coefficient in three situations: (1) when the data consist of two scores for each of N individual persons/items, as in a correlational situation; (2) when the data are arrayed in an ordered 2×2 contingency table, as in a cross-classification situation; or (3) when the data consist of two conditional probabilities (e.g., conditional probability of saying “old” given that the actual state is old, and conditional probability of saying “old” given that the actual state is new), as in an absolute-judgment or detection situation. © 1986, Psychonomic Society, Inc..
