WebAug 10, 2024 · The p -value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis. WebThe formula for the calculation for P-value is. Step 1: Find out the test static Z is. z = p ^ − p 0 p o ( 1 − p 0) n. Where, p ^ = Sample Proportion. P0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z value obtained.
