Stdev excel на русском

Calculates standard deviation based on the entire population given as arguments. The standard deviation is a measure of how widely values are dispersed from the average value (the mean).

Important: This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel.

For more information about the new function, see STDEV.P function.

Syntax

The STDEVP function syntax has the following arguments:

Number1 Required. The first number argument corresponding to a population.

Number2, . Optional. Number arguments 2 to 255 corresponding to a population. You can also use a single array or a reference to an array instead of arguments separated by commas.

Remarks

STDEVP assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the standard deviation using STDEV.

For large sample sizes, STDEV and STDEVP return approximately equal values.

The standard deviation is calculated using the "n" method.

Arguments can either be numbers or names, arrays, or references that contain numbers.

Logical values, and text representations of numbers that you type directly into the list of arguments are counted.

If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.

Arguments that are error values or text that cannot be translated into numbers cause errors.

If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVPA function.

STDEVP uses the following formula:

where x is the sample mean AVERAGE(number1,number2,…) and n is the sample size.

The Excel STDEV function returns the standard deviation for data that represents a sample. To calculate the standard deviation for an entire population, use STDEVP or STDEV.P.

  • number1 — First number or reference in the sample.
  • number2 — [optional] Second number or reference.

The STDEV function calculates the standard deviation for a sample set of data. Standard deviation measures how much variance there is in a set of numbers compared to the average (mean) of the numbers. The STDEV function is meant to estimate standard deviation in a sample. If data represents an entire population, use the STDEVP function.

In the example shown, the formula in F7 is:

Note: Microsoft classifies STDEV as a "compatibility function", now replaced by the STDEV.S function.
