Abstract

Chi-square test of association is a statistical method frequently used in medical research to compare two or more groups of subjects on a certain characteristic to see the numbers or proportions of the subjects having the characteristic are different. The test is appealing because of its mathematical and conceptual simplicity. Unfortunately, it is sometimes misused leading to misinterpretation of a scientific study. In this paper, the uses of chi-square test of association will be described and the situations in which misuses may occur will be emphasized, all illustrated with examples.
