There’s a new measure aggregation type called geometric mean. It’s a way of calculating the average of multiple numbers that is used in various statistical models. The technical definition of geometric mean is the nth root of a product of n numbers.
In practice, the math is fairly simple. With the “average” aggregation type, three numbers are aggregated using ((a + b + c))⁄3. For geometric mean, the equation is ∛(a * b * c).
