the.com/outlier

means A person or thing that sits apart from the main group or pattern — unusual enough to stand out from the rest.

from Built from 'out' plus 'lie' (as in 'to lie, be situated'), so literally something that lies outside — originally a 17th-century English term for property or land detached from the main estate, before statisticians in the 19th century borrowed it for a data point sitting outside the expected range.
