Question 298921
Given: {{{(3+5+5+5+7)/5 = 5}}}
I believe the word that you are looking for is mean.
The mean of the data is 5 (aka average).

On a side note, 5 is also the median and the mode for this set of data.
Median = the number in the middle of the data.
Mode = the number that appears the most often.
