Answer 1

Mean: 89 Median: 92 Mode: 94

Explanation:

For Mean:

In mathematic terms, mean is the average number in the list.. How you find mean is all of the numbers shown in the table divided by the amount of people (In this scenario, it’s test scores.) All of the test scores added up equals 623. There is 7 test scores shown. So, after we divide the two numbers, we get 89.

For Median:

Median is the middle value in a list. But, this is in order. If we putted the numbers we have, we would get 78, 82, 85, 92, 94, 94, 98. If we look at the middle value, out number would be 92.

For Mode:

Mode is the most repeated number in the list. If you look at the list, every number is only shown once, except for 94. 94 is shown twice, so the answer would be 94.
