I don't understand this at all. can someone explain?
ElenaW [278]

Answer:

In order, your numbers are

22, 45, 75, 89, 89, 95, 100

The median is the number that is in the middle numbers of all your numbers. The median is 89, since it is in the very middle.

The mean is all your numbers added together and then divided by how ever many numbers you have. 22 + 45 + 75 + 89 + 89 + 95 + 100 = 515. Since you have 7 numbers, you would divide 515 by 7, which equals 73.5. The mean is 73.5.

The mode is the number that has the most numbers(not sure how to word it) Since 89 has two of the numbers, and no other numbers have duplicates, your mode is 89.
