The average score is:
11.8
We know that the average score is the ratio of the sum of all the scores to the total number of scores.
Here the total number of scores are: 8
Also, the sum of all the scores are:
10.2+11.4+10.5+12.6+12.2+11.6+13.1+12.8=94.4
Hence, the average score is:
[tex]Average\ score=\dfrac{94.4}{8}\\\\Average\ score=11.8[/tex]
