scipy.stats.binom_test

scipy.stats.binom_test(x, n=None, p=0.5)

Perform a test that the probability of success is p.

This is an exact, two-sided test of the null hypothesis that the probability of success in a Bernoulli experiment is p.

Parameters:

x : integer or array_like

the number of successes, or if x has length 2, it is the number of successes and the number of failures.

n : integer

the number of trials. This is ignored if x gives both the number of successes and failures

p : float, optional

The hypothesized probability of success. 0 <= p <= 1. The default value is p = 0.5

Returns:

p-value : float

The p-value of the hypothesis test
