Make sure your data is organized in columns or rows. It’s easier to work with clean and well-structured data.
Step 2: Select the Data Range
Highlight the range of cells that contain the data you want to average.
Selecting a clean range ensures that Excel knows exactly which data points to include in the calculation.
Step 3: Go to the Data Tab
Navigate to the "Data" tab in the Excel ribbon.
This tab contains various tools for data analysis, including the option for calculating a moving average.
Step 4: Click on Data Analysis
In the "Data" tab, find and click on "Data Analysis."

The interval determines how many data points will be averaged together.
Step 8: Choose the Output Range
Select where you want the moving average results to appear.
This can be in the same sheet or a different one. Make sure the output range doesn’t overlap with your data range.
Step 9: Click OK
Finally, click "OK" to generate your moving average.
Excel will calculate and display the moving average based on your settings.
After completing these steps, your moving average will appear in the specified output range, allowing you to visualize trends in your data more easily.
