ISAT - Math Grade 5

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?

2. median 86, mode 81

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.
