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
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?
