Returns the 50th percentile of an expression values in a table.
The behavior of MEDIANX and MEDIAN is different if the expressions return blanks, logical values, or text.
Expressions returning blanks are relevant to MEDIANX, whereas they are ignored by MEDIAN.
The result is blank in case there are no rows in the table returning a non-blank value.
When Expression returns an Integer, the resulting data type of MEDIANX is Variant (Integer for non-ties, Decimal for ties). Assigning a variant to a calculated column is not possible, so a type conversion is required in that case by using CONVERT.
