Adding Random Noise to Data in Excel

1. Select the column of data that you want to add noise to.

2. Go to the Data tab in the ribbon and click on Data Analysis. (Note: If you don't see "Data Analysis" in the ribbon, you may need to enable it by going to "File" "Options" "Add-ins" "Excel Add-ins" "Analysis ToolPak" "OK").

3. In the Data Analysis dialog box, select Random Number Generation and click OK.

4. In the Random Number Generation dialog box, select Normal for the distribution and enter a mean of 0 and a standard deviation of the amount of noise you want to add. You can experiment with different standard deviations to see what looks best.

5. Select the Output Range where you want the random numbers to be generated. Make sure to select a range that is the same size as your original data.

6. Click OK to generate the random numbers.

7. Finally, add the random numbers to your original data by selecting the range where you want the new data to be and entering the formula . This will add the random numbers to your original data without moving the original data points to a different bin.
