Returns the average of the absolute deviations of data points from their mean. AVEDEV is a measure of the variability in a data set.
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.
- AVEDEV is influenced by the unit of measurement in the input data.
- Arguments must either be numbers or be 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 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:
