The Binomial Test is a statistical method used to determine if the proportion of successes in a binary outcome (like yes/no or success/failure) differs from a specified value. It is particularly useful when dealing with small sample sizes and helps assess whether the observed results are due to chance or indicate a significant effect. In a Binomial Test, the null hypothesis typically states that the true proportion of successes is equal to a certain value. By calculating the probability of observing the data under this hypothesis, researchers can decide whether to reject or fail to reject the null hypothesis based on a chosen significance level.
