.. _auto_math_median:

*COMPUTE THE MEDIAN OF A LIST OF NUMBERS*
=========================================

Computes the median value of a list of numbers. Accepts either a comma-separated string or an array of numeric values and returns the middle value (or average of the two middle values for even-length lists). Use this worker whenever a robust central-tendency measure is needed in a workflow.
