Why an average is needed to compare your results?

Answer 1

You need an average to be able to track and see exactly how much of whatever was used. It combines your data to tell you which was used more.

Answer 2

add up all the values and divide by number of values you have.
for example: 2,9,7,5,4,2,2,2,1,15,7
