AVEDEV function

Returns the average of the absolute deviations of data points from their mean. AVEDEV is a measure of the variability in a data set.

Syntax

AVEDEV(number1,number2, ...)

Number1, number2, ...     are 1 to 30 arguments for which you want the average of the absolute deviations.

Remarks

• The arguments must be either numbers or column references that contain numbers.

• If a column reference argument contains text, logical values, or is empty, those values are either ignored or return the #VALUE! error value; however, the value zero is included.

• The equation for average deviation is:

  

AVEDEV is influenced by the unit of measurement in the input data.
