contingency table

a method of presenting results so as to show relationships between two characters which can then be tested statistically by a modified CHI-SQUARED TEST (the heterogeneity chi-square test). For example, eye colour and hair colour might be measured in a sample population and the results presented in a contingency table.

contingency

a critical event such as birth or death or affliction with a particular disease.

contingency coefficient

tabular classification of epidemiological data in horizontal lines and vertical rows, e.g. cause of death vertically and age horizontally, so that each patient appears only once.
