WebApr 9, 2024 · I generated a correlation heatmap of 4 variables using seaborn. In each cell of the heatmap, I would like to include both the correlation and the p-value associated with the correlation. Ideally, the p-value should be on a new line and in brackets. I am trying to use the annot argument for displaying both the correlation and p-value in the heatmap. WebJul 22, 2024 · Suppose we want to find the p-value associated with a z-score of 1.24 in a two-tailed hypothesis test. To find this two-tailed p-value we simply multiplied the one-tailed p-value by two. The p-value is 0.2149. If we use a significance level of α = 0.05, we would fail to reject the null hypothesis of our hypothesis test because this p-value is ...
