a basketball team played six games. in those games, the team won by 8 points, lost by 15, won by 9, won by 11, lost by 1, and won by 12. what was the mean difference in game scores over the six games?
Answer
Explanation:
Step1: Define the data values
Let the point - differences be (8), (- 15), (9), (11), (-1), (12) (a win is a positive value and a loss is a negative value).
Step2: Calculate the sum of the data values
[S=8+( - 15)+9 + 11+( - 1)+12=8 - 15+9+11 - 1+12=(8 + 9+11+12)+(-15 - 1)=40-16 = 24]
Step3: Calculate the mean
The number of data - points (n = 6). The mean (\bar{x}=\frac{S}{n}). So (\bar{x}=\frac{24}{6}=4)
