WebJan 27, 2024 · Conclusion and interpretation. Now that we have the test statistic and the critical value, we can compare them to check whether the null hypothesis of independence of the variables is rejected or not. In our example, test statistic= 15.56> critical value= 3.84146 test statistic = 15.56 > critical value = 3.84146. WebJul 13, 2024 · The number you see is the critical value (or the t -value) for your confidence interval. For example, if you want a t -value for a 90% confidence interval when you have 9 degrees of freedom, go to the bottom of the table, find the column for 90%, and intersect it with the row for df = 9. This gives you a t- value of 1.833 (rounded). how to list columns in python https://mjengr.com
