Question: 227

7. The table below shows the scores of 10 different figure skaters at a skating competition.

  • A. 5.3
  • B. 5.6
  • C. 5.7
  • D. 5.8
  • Correct Answer: C

    Explanation:

    The answer is C

    To calculate the median, list out all scores in order and find the middle number. One student scored a 4.8, 2 scored a 5.3, 2 scored a 5.6, 4 scored a 5.8, and 1 scored a 6.0. So, the list of numbers is 4.8, 5.3, 5.3, 5.6, 5.6, 5.8, 5.8, 5.8, 5.8, 6.0. When the number of terms on a list is even, the median is calculated by the average of the two numbers in the middle: = 5.7.
