How do you find the level of significance

WebFeb 6, 2024 · As a general rule, the significance level (or alpha) is commonly set to 0.05, meaning that the probability of observing the differences seen in your data by chance is just 5%. A higher confidence level (and, thus, a lower p-value) means the results are more significant. If you want higher confidence in your data, set the p-value lower to 0.01.
