Find T Critical Value in Excel

Understanding T Critical Value

The t critical value is integral to hypothesis testing, helping assess if results are due to random chance. It's derived from the t-distribution, which is applicable when dealing with small sample sizes or unknown population standard deviations.

Using Excel's T.INV.2T Function

To calculate the t critical value in Excel, use the T.INV.2T function. It requires a significance level and degrees of freedom, corresponding to the desired confidence interval and sample size minus one, respectively.

Step-by-Step Calculation

Enter the T.INV.2T function in a cell, input the significance level (alpha) for your test, and the degrees of freedom (df). Excel returns the t critical value, which you can use for determining the confidence intervals in your analysis.
