To find the T critical value for a left-tailed test with a significance level of 0.05 and degrees of freedom = 11, we can type the following formula into Excel: T.INV(0.05, 11)

The following examples illustrate how to find the T critical value for a left-tailed test, right-tailed test, and a two-tailed test. Examples of Finding the T Critical Value in Excel This function returns the critical value from the t distribution for a two-tailed test based on the significance level and the degrees of freedom provided. To find the T critical value in Excel for a two-tailed test, you can use the T.INV.2T() function, which uses the following syntax: This function returns the critical value from the t distribution for a one-tailed test based on the significance level and the degrees of freedom provided. probability: The significance level to use.To find the T critical value in Excel for a one-tailed test, you can use the T.INV.() function, which uses the following syntax: Related: How to Find the Z Critical Value in Excel How to Find the T Critical Value in ExcelĮxcel offers two functions to find the T critical value. Using these three values, you can determine the T critical value to be compared with the test statistic. The type of test (one-tailed or two-tailed).A significance level (common choices are 0.01, 0.05, and 0.10).To find the T critical value, you need to specify: The T critical value can be found by using a t distribution table or by using statistical software. If the absolute value of the test statistic is greater than the T critical value, then the results of the test are statistically significant. To determine if the results of the t-test are statistically significant, you can compare the test statistic to a T critical value.
Whenever you conduct a t-test, you will get a test statistic as a result.
