How to use deviation
Deviation is used formally across statistical, scientific, and general contexts to describe any measurable difference from an expected or standard value. It is more technical than 'difference' and implies a meaningful departure rather than mere variety. The word carries neutral connotations in statistics but can suggest wrongdoing in moral or behavioral contexts, particularly in fixed phrases like 'sexual deviation'.
Common phrases
- standard deviation
- deviate from the norm
- significant deviation

A common mistake
Learners sometimes confuse 'deviation' with 'deviance'; deviance refers more specifically to social or moral non-conformity, while deviation is broader and more technical in application.
