Describing something that is not based on experiments or trials, often used in research contexts.
The study used nonexperimental methods to gather data from participants without manipulating any variables.
Nonexperimental → It is formed from "non-" (meaning not) and "experimental" (from Latin "experimentalis", meaning pertaining to experience or trial). The word "nonexperimental" means not related to or involving experimentation or trials.
Think of 'non-' meaning 'not' and 'experimental' relating to 'experience' or 'trial' — so nonexperimental refers to something that is not based on trials or experiments.
