AVEDEV

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. You can also use a single array or a reference to an array instead of arguments separated by commas.

Remarks

• The arguments must be either numbers or names, arrays, or references that contain numbers.
• If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
• The equation for average deviation is:

  

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

Example

AVEDEV(4, 5, 6, 7, 5, 4, 3) equals 1.020408
