The table above shows the distribution of test scores for a group of management trainees. Which score interval contains the median of the 28 scores?
Answer/Solution
28th(50-79)
Steps/Work
Total scores= 2+10+16+10+18 =56, which is odd, therefore the median is the Floor(56/2)= 28th score. And the 37th score is in the 80-89 range, because 50-79 only reference 28 scores.
