What is binary hypothesis testing?

Binary Hypothesis Testing is to decide between 2 hypotheses based on the observation (random). Model contains: 1. Hypothesis and a-priori probability 2. Observation 3. Connection b/w hypotheses and observation 4.

Which statistical test for binary data?

McNemar test

You would perform McNemar's test if you were interested in the marginal frequencies of two binary outcomes. These binary outcomes may be the same outcome variable on matched pairs (like a case-control study) or two outcome variables from a single group.

How do you test a binary variable?

In the specific case of two binary variables, one can also use a proportion test to decide whether the proportion of the population with a given value for X is the same, over the two values of Y. The link between two binary variables is studied with the proportion test.
