Have you ever heard of the term covariance?

Yeah, I think it's related to statistics, right?

Root Explanation

Covariance → It is formed from "co-" (meaning together) and "variancia" (from Latin "varians", meaning varying or changing). The word describes the measure of how two variables change together, indicating their joint variability.

Memory Tip

Think of two things changing 'together' ('co-') and how they 'vary' ('variancia') — that's what covariance measures.
