Answer 2

Look at all the answer choices. Median would be a better choice than mean for the data sets that have one value that is much lower or higher than the other values.

Answer 5

For example. Look at A. The values are 45, 47, 49, 52, and 94. Notice how 94 is a lot higher than the rest of the values. That will influence the mean in a way that it won't accurately reflect the center. That means that median would be a better choice. So A is one of the answers.
Can you find another answer choice like this?
