Question

Four judges score dancers on their performance. The average of the four judges' scores for 10 dancers are listed.

9.25, 9.25, 9.75, 10.25, 10.75, 10.75, 11.25, 11.75, 11.75, 11.75
What is the mean (average) score?

Answer 1

To find the mean (average) score, add up all the scores and divide by the number of scores.

Step-by-step explanation:

To find the mean (average) score, you need to add up all the scores and divide by the number of scores. In this case, the sum of the scores is 9.25 + 9.25 + 9.75 + 10.25 + 10.75 + 10.75 + 11.25 + 11.75 + 11.75 + 11.75 = 107.25. Since there are 10 dancers, you divide the sum by 10 to get the average: 107.25 ÷ 10 = 10.725.
