McNemar's Test Should Be Used When

McNemar's test should be used when:

A) We have more than two variables.
B) We have a nominal dichotomous independent variable and a severely skewed dependent variable that is at the ordinal, interval or ratio level of measurement.
C) We want to examine change from pretest to posttest within one group on a nominal variable.
D) We want to compare sample proportions on a single variable to proportions known to exist in the broader population.
