De McNemar toets is een toets voor het vergelijken van gepaarde proporties. Bijvoorbeeld bij het vergelijken van een voor en een na meting. De toets wordt ook wel McNemar's test of symmetry of McNemar symmetry chi-square test genoemd, omdat er gekeken wordt of de cellen van de 2x2 tabel symmetrisch verdeeld zijn.
An interesting observation when interpreting McNemar's test is that the elements of the main diagonal do not contribute to the decision about whether (in the above example) pre- or post-treatment condition is more favourable. Thus, the sum b + c can be small and statistical power of the tests described above can be low even though the number of pairs a + b + c + d is large (see second example above). WebThe McNemar test (also known as the paired or matched chi-square) provides a way of testing the hypotheses in such designs. An example for the use of this statistic may be …
