How to Find Variance on Microsoft Excel
Calculating variance in Microsoft Excel is an essential skill for analyzing data variability. Follow these steps to find variance efficiently:
-
Step 1. Enter Your Data
Begin by entering the data set for which you want to calculate the variance into a column or row in your Excel worksheet.
-
Step 2. Select the Target Cell
Click on the cell where you want the variance result to appear. This is where you will input the variance formula.
-
Step 3. Use the VAR.P or VAR.S Function
For population variance, type “=VAR.P(” followed by the range of your data (e.g., “=VAR.P(A1:A10)”).
For sample variance, use “=VAR.S(” followed by the data range (e.g., “=VAR.S(A1:A10)”).
-
Step 4. Press ‘Enter’
Press the “Enter” key to calculate the variance. The result will appear in the selected cell, providing the measure of data variability.
-
Step 5. Verify and Interpret the Result
Review the calculated variance to ensure accuracy. Use this value to interpret the spread of your data, aiding in your statistical data analysis.

FAQs
How do I find variance in Excel?
Use the VAR.P function for population variance or VAR.S for sample variance.
What is the difference between VAR.P and VAR.S?
VAR.P calculates variance for an entire population while VAR.S calculates variance for a sample.
Can I calculate variance for non-adjacent cells?
Yes, list the cells separated by commas within the VAR.P or VAR.S function.
Does Excel automatically update the variance if my data changes?
Yes, if your data range is referenced correctly, the variance will update automatically.
Can I calculate variance for data in rows instead of columns?
Yes, the VAR.P and VAR.S functions work for both rows and columns of data.
