How To Run ANOVA in Microsoft Excel
Microsoft Excel facilitates the execution of Analysis of Variance (ANOVA), a statistical method used to compare the means of three or more samples. By integrating ANOVA into your Excel toolkit, you’ll unlock the ability to discern significant differences between group means, thereby enhancing your research and data interpretation capabilities.
How To Run ANOVA in Microsoft Excel
Executing an Analysis of Variance in Microsoft Excel is a powerful technique for comparing datasets. Follow these steps to accurately perform ANOVA within Excel.

Step 5. Input Your Data into the ANOVA Tool
In the ANOVA dialog box, specify the input range of your data, ensuring to include both the dependent and independent variable columns. Select options such as “Labels in First Row” if your data range includes column headers. Choose an output range where you want Excel to display the ANOVA results.
