It is less than the standard threshold of significance, 0.05. ![]() The function returns the p-value as 0.008. The third argument, 2, denotes a two-tailed T-Test, and the fourth argument, 1, refers to a paired T-Test Excel. ![]() Please Note: The cell ranges A2:A16 and B2:B16 are the two arrays we need to compare, so they are the first and second arguments. Step 1: Choose cell D3 and enter the two sample T-Test in Excel function as: Here are the steps to use the T-Test in Excel function in this scenario. Since the data set values are before-after measurements, we consider paired T-test. The second table is where we display the T-Test result. While the null hypothesis is that there is no difference in the mean values of the two samples, the alternate one implies a significant difference. It is a two-tailed T-Test, as we are not making a hypothesis whether the therapy reduced the stress levels. Finally, from the Test() outcome, make the necessary inferences.Ĭonsider the following table that shows the stress levels of a group before (in column A) and after (in column B) attending a therapy.Then, provide the tails argument (one or two-tailed T-Test) and decide the type based on the T-Test type (paired T-Test Excel, Two sample equal or unequal variance T-Tests). Enter the first two array arguments by selecting the first and second data sets.Enter the T-Test in Excel formula by selecting the Test() function, accessible using Formulas > More Functions > Statistical.Then, choose the cell where you want to display the T-Test result, the p-value.First, ensure you have your data sets in a spreadsheet.While 1 is for Paired T-Test, 2 and 3 denote Two sample equal and unequal variance T-Tests, respectively.įollowing are the steps for the T-test in excel. If the value is 1, it indicates the one-tailed distribution if the value is 2, it means two-tailed distribution. tails: This denotes the distribution tail used in a T-Test in Excel. ![]() Unlike other functions, all the T-Test arguments in Excel are mandatory.
