# AVEDEV

AVEDEV(number1, number2 [,number3] [..])

Returns the average deviation of the numerical values.

 number1 The first number. number2 The second number. number3 (Optional) The third number.

 REMARKS
 * For an illustrated example refer to the [[Dispersion]] page.* The average deviation is a measure of dispersion.* This function returns the average of the absolute deviations from the mean.* This function is a measure of the variability in a data set.* You can also use a single array or a reference to an array instead of arguments separated by commas.* The arguments must be either numbers or names, arrays, or references that contain numbers.* If any of the arguments are empty, then these are ignored.* If any of the arguments contain text or logical values, then these are ignored.* If any of the arguments are zero, then these are counted.* If any of the arguments are not numeric, then #VALUE! is returned.* You can have a maximum of 255 arguments.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com

 1 - What is the average deviation of these values from their mean. The mean value is 0.667.2 - What is the average deviation of these values from their mean. Zeros are included so the mean is 1.875.3 - What is the average deviation of these values from their mean. The mean value is 0.4 - What is the average deviation of these values from their mean. The mean value is (4+2+5)/3.
