That man's weight has to show some statistics (9)
I believe the answer is:
histogram
'show some statistics' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'that man's weight has to' is the wordplay.
I cannot really understand how this works, but
'man's' could be 'his' (belonging to a man) and 'his' is found within the answer.
'weight' could be 'gram' (unit of weight) and 'gram' is found within the answer.
'to' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for histogram that I've seen before include "Representation blocked" , "plot" , "statistical chart" , "Statistical diagram" , "Chart showing statistics" .)
