Solution & Step-by-step Explanation

To find the average score difference across all nine games, we first calculate the total sum of the score differences.
Sum of score differences in won games:

12+3+8+4+1=28
Sum of score differences in lost games:

(−4)+(−1)+(−2)+(−3)=−10
Total sum of score differences for all 9 games:

Total Sum=28+(−10)=18
Total number of games = 9
