WebThe most common formula to calculate a Z score involves the observation (X), the hypothesized mean (μ), and hypothesized standard deviation (σ): Enter any number for Z to calculate the P value from Z score statistics. Entering your Z score as positive or negative will result in the same P value, because this test is two-sided. WebFeb 13, 2024 · To determine the p-value, you need to know the distribution of your test statistic under the assumption that the null hypothesis is true.Then, with the help of the cumulative distribution function (cdf) of this distribution, we can express the probability of the test statistics being at least as extreme as its value x for the sample:Left-tailed test: p …
