Standard displayed by women or men (4)
I believe the answer is:
norm
'standard' is the definition.
(norm is a kind of standard)
'displayed by women or men' is the wordplay.
'displayed by' says the answer is hidden in the clue.
'NORM' is hidden within 'women or men'.
(Other definitions for norm that I've seen before include "(The) accepted way" , "Rule, standard, pattern" , "Yardstick" , "Drawing stick" , "Expected standard" .)
