The binomial test is useful to test hypotheses about the probability ($${\displaystyle \pi }$$) of success: $${\displaystyle H_{0}\colon \pi =\pi _{0}}$$ where $${\displaystyle \pi _{0}}$$ is a user-defined value between 0 and 1.

They are used for a sample of one binary categorical variable. For example, if we want to test whether a coin is fair, we might flip it 100 times and count how many heads we get.
