Through, T-test in Excel you can decide the statistical significant differences between the datasets. In order words, it is a two-sample T-test which compare the means of two samples. In this blog, you will read the method to perform a T Test in Excel. For more help related to Excel, go to Microsoft via www.office.com/setup.
Method To Perform a T Test in Excel:
1. Checking and Loading Analysis Toolpak Add-In:
If you want to activate the Analysis Toolpak, then you should choose the FILE tab and then choose Options. Now in the Options dialogue box, you should choose Add-Ins from the tabs which are on the left side of the screen. Here at the bottom of the window, you should choose the Manage drop-down menu and then choose Excel Add-ins. And then tap on Go button. At this point, you need to check the check-box which is next to Analysis Toolpak and then tap on OK button. Lastly, the Analysis Toolpak is active and then you should apply F-Tests and T-Tests.
2. Perform F-Test and a T-Test in Excel:
First, you need to enter two datasets into a spreadsheet. After this, you should choose the Data tab and then tap on Data Analysis. Now, you should choose F-Test Two-Sample for Variances from the list and then tap on OK button. Here, you need to choose the Variable 1 Range and Variable 2 Range and then you need to set the Alpha. At this point, you need to choose a cell for the top left side of the output and it will fill 3 columns and 10 rows and then tap on OK button. You should view the F-Test results to check if there is a significant difference between the variances. It will give three important values: F, P(F<=f) one-tail and F Critical one-tail. Here, you came to know if there is a difference between the variances and then choose the appropriate T-Test. Next, you should choose the Data tab and then tap on Data Analysis. After this, you should choose either t-Test: Two-Sample Assuming Equal Variances or t-Test: Two-Sample Assuming Unequal Variances. Here in the same dialogue box, you need to enter the details of the analysis. If you want to start, then you have to choose the ranges which contain the samples for Variable 1 Range and Variable 2 Range. If in case, you want to test for no difference between the means, then you should set the Hypothesized Mean Difference to zero. At this point, you should Set the significance level Alpha and then choose a cell for the top left side of the output. It will fill 3 columns and 14 rows and then choose OK button. At last, you should Review the results in order to decide if you find a significant difference between the means.
With this above method, you can perform a T Test in Excel. If the customer wants any type of details related to Excel, then visit to the official site of Microsoft through office.com/setup.
