That's the wrong question. The right question is, why is adding a key parameter useful? The statistics module is for calculating statistics. Think of it as like a button on your scientific calculator in STATS mode. It's not designed for tasks like finding the employee with the median salary or the highest performing sales representative for the third quarter of 2017.
