Question

A basketball team scored 18,24,16,20 and 28 points in their first five games. how will the median change if the team scores 30 points in their sixth game?

Answer 1

By plus 2 points

Explanation:

The median average is the midpoint in a list of acceding values, in this case the median is 16,18,20,24,28 so its 20. But after they score 30 points in their next game, the median will be 16,18,20,24,28,30. Since there is 2 midpoints we have to take the mean average of both, which is just adding up the value of all terms and then dividing by the number of terms in the list.

(20+24)/2 = 22

Our median average before the sixth game is 20 and after its 22, do the change in median is +2
