Considerations when using the VARX.S function
- VARX.S evaluates expression for each row of table and returns the variance of expression; on the assumption that table refers to a sample of the population. If table represents the entire population, then you should compute the variance by using VARX.P.
- VAR.S uses the following formula:∑(x – x̃)²/(n-1)where x̃ is the average value of x for the sample populationand n is the population size
- Blank rows are filtered out from columnName and not considered in the calculations.
- An error is returned if columnName contains less than 2 non-blank rows.
