Answer:
Finding the average is a very straightforward concept. If you have a set of numbers, the average is found by adding all numbers in the set and dividing their sum by the total number of numbers added in the set.
example;
16, 17, 5, 27, 30, 20, 4, 1, 19, 9
add all 10 of these numbers together
16 + 17+ 5+27+30+4+1+19+9 = 148
divide 128 by 10
148 / 10 = 14.8
14.8 is the average
