# AVERAGEIF Function

The AVERAGEIF function is one of the statistical functions. It is used to analyze the range of data and find the average value of all numbers in a range of cells, based on the specified criterion.

The AVERAGEIF function syntax is:

AVERAGEIF(cell-range, selection-criteria [,average-range])

where

cell-range is the selected range of cells to apply the criterion to.

selection-criteria is the criterion you wish to apply, a value entered manually or included into the cell you make reference to.

average-range is the selected range of cells you need to find the average in.

Note: average-range is an optional argument. If it is omitted, the function will find the average in cell-range.
