See VAR
In Google Sheets, the function VAR.S is used to calculate the sample variance of a set of values. It calculates the variance based on a sample of data, rather than the entire population.
The syntax for the VAR.S function is as follows: VAR.S(value1, [value2, …])
value1, value2, …: These are the individual values or ranges of cells that you want to include in the calculation of the sample variance. You can specify multiple values or ranges by separating them with commas.
The VAR.S function measures the dispersion or spread of the values in the sample. It tells you how much the values deviate from the average (mean) value. A higher variance indicates greater variability, while a lower variance suggests less variability.
