Powerful p-value calculator online: calculate statistical significance using a Z-test or T-test statistic (z test calculator / t-test calculator). P-value formula, Z-score formula, T-statistic formula and explanation of the inference procedure.
A P-value calculator is used to determine the statistical significance of an observed result in hypothesis testing. It takes as input the observed test statistic, the null hypothesis, and the relevant parameters of the statistical test (such as degrees of freedom), and computes the p-value.
17 cze 2024 · P value formula. P-values are calculated either manually from the p-value tables or through spreadsheets or statistical software. P-values are calculated from the z-score, t-score, or chi-square value obtained from various tests. Once the scores are obtained, the values are used to determine the p-value for that specific score.

This p-value calculator helps you to quickly and easily calculate the right-tailed, left-tailed, or two-tailed p-values for a given z-score. It also generates a normal curve and shades in the area that represents the p-value.
To find the p value for your sample, do the following: Identify the correct test statistic. Calculate the test statistic using the relevant properties of your sample.
