Mc Nemar's Test
In statistics, McNemar's test is a normal approximation used on nominal data. It is applied to 2 × 2 contingency tables with a dichotomous trait, with matched pairs of subjects, to determine whether the row and column marginal frequencies are equal ("marginal homogeneity"). It is named after Quinn McNemar, who introduced it in 1947. An application of the test in genetics is the transmission disequilibrium test for detecting genetic linkage.

Famous quotes containing the word test:
“There is held to be no surer test of civilisation than the increase per head of the consumption of alcohol and tobacco. Yet alcohol and tobacco are recognisable poisons, so that their consumption has only to be carried far enough to destroy civilisation altogether.”
—Havelock Ellis (1859–1939)
