The AVERAGEA function takes a column and averages the numbers, but also handles non-numeric data types according to the following rules:
+
+
*The function takes a table as its first argument, and an expression as the second argument.
+
*The AVERAGEX function enables you to evaluate expressions for each row of a table, and then take the resulting set of values and calculate its arithmetic mean.
+
*You cannot include non-numeric or null cells. Both the table and expression arguments are required.
+
*When there are no rows to aggregate, the function returns a blank. When there are rows, but none of them meet the specified criteria, then the function returns 0.
