VAR formula calculates the variance of a set of numerical values. Variance is a measure of how spread out a set of data is in relation to the mean. This formula is commonly used in statistical analysis to measure the variability or diversity of a dataset.

- Similar formulas to
VAR formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:
- value1 (required):
The first value or range of cells that contain the numerical data
- value2, ... (optional):
Additional values or ranges of cells that contain the numerical data
ExamplesHere are a few example use cases that explain how to use the
VAR formula in Google Sheets.
Calculating variance of a data set
VAR formula can be used to calculate the variance of a set of numerical values. This can be useful in statistical analysis to determine the diversity of a dataset.
Comparing variability of datasets
By using the
VAR formula to calculate the variance of two or more datasets, you can compare their variability and determine which dataset has a larger spread of data.
A dataset with a large variance may indicate the presence of outliers. By using the
VAR formula to calculate the variance, you can identify potential outliers that may need to be further investigated or removed from the dataset.
VAR not working? Here are some common mistakes people make when using the
VAR Google Sheets Formula:
Forgetting to enter any values
If you forget to enter any values for the function to calculate the variance, it will return an error. Make sure you have entered at least one value before using the function.
Entering non-numerical values
VAR function can only calculate the variance of numerical values. If you enter any non-numerical values, the function will return an error. Make sure all values entered are numerical.
Forgetting to close parentheses
If you forget to close the parentheses that enclose the values you want to calculate the variance of, the function will return an error. Make sure to close all parentheses when using the function.
The following functions are similar to
VAR or are often used with it in a formula:
The AVERAGE function calculates the average (arithmetic mean) of the values passed to it. It is commonly used to find the average of a range of cells containing numerical data.
STDEVfunction calculates the standard deviation of a set of numbers. It measures the amount of variation or dispersion of a set of values from the average (mean) value. It is commonly used in statistics to determine the spread of a data set. The values can be supplied as individual cells, ranges, or constants.
STDEVPfunction calculates the standard deviation of an entire population. It is commonly used in statistical analysis to measure the amount of variation or dispersion in a set of data. This function takes in at least two numerical arguments representing the values in the population for which you want to calculate the standard deviation.
COVARformula calculates the covariance of two sets of data, which measures how much two variables change together. It is commonly used in statistical analysis to determine the relationship between two variables. The resulting value can be positive or negative, with a higher value indicating a stronger relationship.
CORRELformula returns the correlation coefficient between two sets of data. This coefficient represents the strength of the linear relationship between the two sets of data, with values ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation).
