Describing a result or value that is not important or does not have a meaningful effect, especially in statistics.
The study found that the changes in temperature were nonsignificant and did not affect the results.
Nonsignificant → It is formed from "non-" (meaning not) and "significant" (from Latin "significare", meaning to signify or indicate). The word "nonsignificant" means not indicating or not having importance.
Think of 'not' ('non-') and 'indicating' ('significant') to remember that 'nonsignificant' means something that does not indicate importance.
