Question

A basketball team played six games. In those​ games, the team won by 7 ​points, lost by 3 ​, won by ​8 , won by 9 ​, lost by ​2, and won by 11. What was the mean difference in game scores over the six​ games?

Answer 1

To find the mean difference in game scores, we need to calculate the sum of the differences and divide it by the number of games.

The differences in game scores are:
7 (game 1)
-3 (game 2)
8 (game 3)
9 (game 4)
-2 (game 5)
11 (game 6)

The sum of the differences is:
7 + (-3) + 8 + 9 + (-2) + 11 = 30

There are 6 games in total.

Therefore, the mean difference in game scores over the six games is:
30/6 = 5
