| Test | Purpose |
|---|---|
| Binomial exact | Test if the proportion with the outcome of interest is equal to a hypothesized value. Uses the binomial distribution and computes an exact p-value. The test is conservative, that is, the type I error is guaranteed to be less than or equal to the desired significance level. Recommended for small sample sizes. |
| Score Z | Test if the proportion with the outcome of interest is equal to a hypothesized value. Uses the score statistic and computes an asymptotic p-value. Equivalent to Pearson's X² test. Recommended for general use. |
