Translate a Statistical Concept Someone Is Misusing

The term is being used in the meeting and it means something slightly different from what the person saying it thinks it means. This explains what it actually measures, why the common version is wrong, a concrete example, and what to say or think instead. Then the meeting can continue with better information in it.
