Alpha, the significance level, is the probability that you will make the mistake of rejecting the null hypothesis when in fact it is true. The p-value measures the probability of getting a more extreme value than the one you got from the experiment . If the p-value is greater than alpha, you accept the null hypothesis.
P-value vs alpha matters because p-value reflects the likelihood of observed results, while alpha sets the boundary for rejecting the null hypothesis. |
26 сент. 2022 г. · P-value tells you where you stand with reference to the alpha value. If your p-value is less than the alpha value, you reject the null hypothesis. |
