small p-value means that your data would be surprising under the null hypothesis, which counts as evidence against it. This tool converts a z-score (the standard-normal test statistic) into a p-value — the probability of observing a result at least as extreme as yours if the null hypothesis is true. The left-tailed value is P(Z ≤ z), the right-tailed value is P(Z ≥ z), and the two-tailed value is 2 × P(Z ≥ |z|) — double the smaller tail. All come from the standard-normal cumulative distribution, so this tool applies to z-tests and large-sample approximations, and the result sits right on the border of significance. This tool converts a z-score into a p-value.Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:Choose a test:
