WebApr 11, 2024 · However, since the p-value is just a value, we need to compare it with the critical value (⍺): p_value > ⍺ (Critical value): Fail to reject the null hypothesis of the statistical test. p_value ≤ ⍺ (Critical value): Reject the null hypothesis of the statistical test. The critical value that most statisticians choose is ⍺ = 0.05.

WebMar 6, 2024 · A p-value, or probability value, is a number describing how likely it is that your data would have occurred by random chance (i.e. that the null hypothesis is true). The level of statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis.
