Did you notice any deviation in the results of our last experiment?

Root Explanation

Deviation → It is formed from "de-" (meaning away from) and "via" (meaning way or path). The word describes a departure from the usual way or path.

Memory Tip

Think of moving 'away from' ('de-') the usual 'path' ('via') — that's why deviation means a change from the expected course.
