The most obvious way define anything
to as 'normal' or 'abnormal is in terms of the number
oftimes
it
is observed.
Statistics is about numbers

Counterpoint:Benefits versus
problems
When someone is

julgued life, there is no
benefitto them being labelled as abnormal, and this
might carry a

stigma. Therefore labelling someone abnormal
justbecause they are statistically usual is likely to
do more harm than
good.
Limitationat usual characteristics can also be positive
P-Ifvery few people display a characteristic, then the behaviour
