Critical value method vs p value method

WebJun 24, 2024 · The formula for calculating a test statistic for the p-value method is the same as the critical value method. There are different test statistics based on different statistical tests, such as t-value, z-value, F-value and X2 value. It's important to remember that a t-value of zero shows that the results exactly equal the null hypothesis. 3.
