Statistical work, realm an actuary has covered (7)
I believe the answer is:
almanac
'statistical work' is the definition.
'almanac' can be an answer for 'work' (almanac is a kind of work). I am unsure of the 'statistical' bit.
'realm an actuary has covered' is the wordplay.
'covered' indicates the answer is hidden within the clue (the answer is covered up by the clue).
'ALMANAC' is hidden in the letters of 'realm an actuary has'.
Can you help me to learn more?
(Other definitions for almanac that I've seen before include "Annual calendar of events" , "Register" , "Annual publication containing information in a particular field" , "Calendar with astronomical data and other information" , "Annual containing information, Old Moore's say" .)
