Thank you !!!!!!!!!!!!!!!!!!!!!!!

Answer 1

The mean is the average. To find it, you add all of the numbers together.

2 + 8.7 + 11.9 + 3.3 + 4.2 + 2.2 + 13.4 = 45.7

Now you divide the total by the amount of numbers you added. Because you added 7 numbers, you divide 45.7 by 7.

45.7 ÷ 7 = 6.52 (This is the mean.)

To find the median you have to put all of the numbers in order of least to greatest.

2   2.2   3.3   4.2   8.7   11.9   13.4

The median is the number in the very middle. In this case, it is 4.2.
