If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVPA function. How to Calculate Standard Deviation in Excel: 7 Steps. It can aggregate data in any dimension, and can be used at REQUEST level as well. Empty cells, logical values, text, or error values in the array or reference are ignored.Īrguments that are error values or text that cannot be translated into numbers cause errors. The STDDEV aggregation returns the standard deviation for data that represents a sample (realized by the division by n-1 in the formula), similarly to the STDEV.S function in Microsoft Excel. If an argument is an array or reference, only numbers in that array or reference are counted. Logical values, and text representations of numbers that you type directly into the list of arguments are counted. The standard deviation is calculated using the "n" method.Īrguments can either be numbers or names, arrays, or references that contain numbers. If your data represents a sample of the population, then compute the standard deviation using STDEV.įor large sample sizes, STDEV.S and STDEV.P return approximately equal values. STDEV.P assumes that its arguments are the entire population. You can also use a single array or a reference to an array instead of arguments separated by commas.

Number arguments 2 to 254 corresponding to a population. The first number argument corresponding to a population. The STDEV.P function syntax has the following arguments: The standard deviation is a measure of how widely values are dispersed from the average value (the mean). LessĬalculates standard deviation based on the entire population given as arguments (ignores logical values and text).
