Nine children took a science test and their scores were:
97, 93, 92, 87, 86, 81, 81, 78 and 74.
What was the median score and the mode?
- median 91, mode 23
- median 86, mode 81
- median 85, mode 86
- median 81, mode 85
- median 97, mode 74
The correct answer is B. The median is the middle number in an ordered list of data (highest to lowest or lowest to highest). 86 is the fifth or middle number out of nine. The mode is the number that appears most often. 81 is the mode because it is the only number that appears more than once in this list.
