Question: What

What is his mean
examination result?
To
find the average
(or mean)
we add up all the scores in the list and divide the total by the number of
subjects.
i.e.
75 + 85 + 40 +65 +55 = 320 = Total.
Divide
this by 5 because there are 5 subjects in the list - i.e.
320/5 = 64
John's
average (mean) score in his tests is 64.
