Should I use Chi-squared or exact binomial test?

WebExact Methods. Exact methods can be useful in situations where the asymptotic assumptions are not met. Standard asymptotic methods are based on the assumption that the test statistic follows a particular distribution when the sample size is sufficiently large. When the sample size is not large, asymptotic results may not be valid, with the ... WebJan 14, 2024 · $\begingroup$ Various tests comparing two binomial proportions are very similar to chi-sq test on a $2\times 2$ table, Some versions use continuity corrections for small sample sizes, but that usually makes little difference in P-value.
