In hypothesis testing, a critical value is a point on a distribution graph that is analyzed alongside a test statistic to confirm if a null hypothesis—a commonly accepted fact in a study which researchers aim to disprove—should be rejected.
Here we discuss how to calculate hypothesis testing along with practical examples.

In a two-tailed test, the p-value is the probability of getting a value for the test statistic at least as unlikely as the value from the sample. To test the hypothesis in the p-value approach, compare the p-value to the level of significance. If the p-value is less than or equal to the level of signifance, reject the null hypothesis.
