Agreement of statisticians involved in a survey (9)
I believe the answer is:
consensus
'agreement' is the definition.
(I know that consensus is a type of agreement)
'statisticians involved in a survey' is the wordplay.
'statisticians' becomes 'ons' (I can't explain this - if you can you should believe this answer much more).
'involved in' indicates putting letters inside.
'a survey' becomes 'census' (I've seen this before).
'ons' put into 'census' is 'CONSENSUS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for consensus that I've seen before include "General agreement" , "Majority view" , "Unanimity" , "General opinion" , "agreed" .)
