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
