# STDEVA

Formulas / STDEVA
Calculate the standard deviation for a sample of data.
`STDEVA(value1, [value2], ...)`
• value1, value2, ... - 1 to 30 values from a sample of a population

## Examples

• `=STDEVA(A3:A12)`

If you want to calculate the standard deviation of a set of numbers in column A of your Sourcetable sheet, you can use the STDEVA function. For example, this will calculate the standard deviation of the breaking strength for all the items in column A.

• `=STDEVA(A3:A12)`

The STDEVA function is useful when you want to measure the spread of a set of values in a dataset. For instance, if you have a set of test scores in column A, you could use the STDEVA function to calculate the standard deviation of those scores.

• `=STDEVA(A3,B3,C3)`

The STDEVA function can also be used to calculate the standard deviation of a set of numbers that are not in a single column. For example, if you have a set of numbers in cells A3, B3, and C3, you can use the STDEVA function to calculate the standard deviation of those numbers.

• `=STDEVA(A3:C12)`

You can use the STDEVA function to calculate the standard deviation of a set of numbers that are spread across multiple columns. For example, if you have a set of numbers in columns A, B, and C, you can use the STDEVA function to calculate the standard deviation of those numbers.

## Summary

The STDEVA function calculates the standard deviation of a sample population, measuring the spread of values from the average. It assumes that the arguments are from the population.

• The STDEVA function calculates standard deviation for a sample of data using the "n-1" method, assuming the data is a sample of a population.
• To calculate standard deviation for an entire population, use the STDEV or STDEV.P functions instead.
