WebUse the exact binomial test if you have a small sample size or an extreme success/failure probability that invalidates the chi-square and G tests. The exact binomial also applies when you have a one-tail test. The exact binomial test has two conditions: independence, and. at least nπ ≥ 5 n π ≥ 5 successes or n(1−π) ≥ 5 n ( 1 − π ...

Mathwords: Binomial Probability Formula

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. If in a sample of size $${\displaystyle n}$$ there are $${\displaystyle k}$$ … See more In statistics, the binomial test is an exact test of the statistical significance of deviations from a theoretically expected distribution of observations into two categories using sample data. See more Suppose we have a board game that depends on the roll of one die and attaches special importance to rolling a 6. In a particular game, the die is rolled 235 times, and 6 comes up 51 times.
