MEDIAN |
The MEDIAN function calculates the median of the values of an expression. The median is the middle number in a given sequence of numbers.
Return Value
DECIMAL
Syntax
MEDIAN(expression [dimensions])
Arguments
The expression whose median value is to be calculated.
The dimensions of the result. By default, MEDIAN returns a single value. When you indicate one or more dimensions for the results, MEDIAN calculates a median for each value of the dimensions that are specified and returns an array of values. Each dimension must be a dimension of expression. You cannot use a related dimension as the dimensions argument.
Notes
NA Values and MEDIAN
MEDIAN is affected by the NASKIP option in the same manner as other aggregate functions. When NASKIP is set to YES (the default), MEDIAN ignores NA values and returns the median of the values that are not NA. When NASKIP is set to NO, MEDIAN returns NA when any value of the expression is NA. When all the values of the expression are NA, MEDIAN returns NA for either setting of NASKIP.
