WebThe significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of ... WebAug 7, 2024 · Your desired confidence level is usually one minus the alpha (α) value you used in your statistical test: Confidence level = 1 − a. So if you use an alpha value of p < 0.05 for statistical significance, then your confidence level would be 1 − 0.05 = 0.95, or 95%. When do you use confidence intervals?
