How to Calculate Variance in Google Sheets
Understanding Variance
Variance is a statistical function that measures the spread of a dataset around its mean. It's calculated by averaging the squared differences from the mean. In Google Sheets, variance can be calculated for both samples and populations using different functions.
Calculating Sample Variance
To calculate variance for a sample dataset in Google Sheets, use the VAR or VAR.S function. The syntax for the VAR function is VAR(column), where "column" represents the range of your data. Examples include =VAR(A2:A100) or =VAR(1,2,3,4,5,6,7,8,9,10).
Calculating Population Variance
For calculating variance across an entire population, use the VARP or VAR.P function. These functions also use the same syntax as VAR. Example: =VARP(A2:A100).
Handling Text and Errors
Use the VARA function to calculate variance when your dataset includes text values, interpreting them as 0. Be aware that VAR functions will return the #DIV/0! error if fewer than two values are supplied, and they will return an error if all values are text.
Manual Calculation
Variance can also be calculated manually. First, use =AVERAGE(number1, [number2], ...) to calculate the mean. Subtract the mean from each number in the dataset, square the result, and then average these squared differences using =AVERAGE(result1, [result2], ...).
Examples
Examples of variance calculations include: =VAR(table_name!price), =VAR(A2:A100), or =VAR(1,2,3,4,5,6,7,8,9,10).
