S1.5.4 - discrete uniform distribution

The discrete uniform distribution.; The mean and variance of this distribution.

Use discrete uniform distribution to connect the rule to the data and decision in the question.

This matters because discrete uniform distribution determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply discrete uniform distribution to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: discrete uniform distribution is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
