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?

1 answer

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
