Indicate average value (4)
I believe the answer is:
mean
This clue is a double definition.
'indicate' is the first definition.
(thesaurus)
'average value' is the second definition.
(Other definitions for mean that I've seen before include "Stingy in average way" , "Stand for - penny-pinching" , "The average could be miserly" , "intimate" , "Type of average" .)
