Answer:
Step-by-step explanation:
Mean = Sum of scores/number of games
[tex]=\frac{4+10+7+9+2+11+4+9+2+6}{10}\\\\=\frac{64}{10}\\\\[/tex]
Mean = 6.4
4,10,7,9,2,11,4,9,2,6
Ascending order: 2,2,4,4,6,7,9,9,10,11
Median is the middle term. As number of terms is even number (10),
We have to find the mean of middle terms. ie median of 5th and 6th term
[tex]Median=\frac{6+7}{2}\\\\=\frac{13}{2}[/tex]
Median = 6.5
Range = Maximum score - minimum score
= 11 - 2
Range = 9
