Etymology
Origin of norm
First recorded in 1820–30; from Latin norma “carpenter's square, rule, pattern”
Explanation
A statistical average is called the norm. If you live in a town made up mostly of farmers but your trade is basket weaving, then you're outside the norm. The noun norm is from the Latin word norma, which was a carpenter's square or pattern used in construction to make regular corners. Now we use norm for anything that sets a standard. You can score within the norm on a standardized test, score above the norm on an IQ test, or fall below the norm in acceptable standards of dress if you wear a halter top and cut-off jeans to a formal ball.
