McNemar's test to analyze a matched casecontrol studyMcNemar's test is used to compare paired proportions. It can be used to analyze retrospective casecontrol studies, where each case is matched to a particular control. Or it can be used to analyze experimental studies, where the two treatments are given to matched subjects. Read an example with explanation.
Use McNemar's test (and this calculator) only when you are analyzing matched pairs. Each value you enter above represents a number of PAIRS. The total number of subjects in the study is twice the total of the values you enter above.
