Measures of Association.
Elashoff, Janet Dixon; Dunbar, Charles R.
A common problem in educational research is measuring the degree of relationship or association between two variables. Many investigators habitually use Pearson's product-moment correlation coefficient or a transformation of x2. In the past two decades, however, a variety of association measures have been introduced in the statistics literature. This report contains a review of available association measures, supplemented by discussion of the several factors involved in selecting a measure of association such as the types of variables (continuous, ranked, ordered) and the type of association expected (linear, monotone, general). Examples illustrate the necessary calculations and provide comparisons among the measures. (Author)
