Question

Find the mean and median of the data below. Answer to the nearest hundredth.

8, 140, 22, 15, 18, 9, 25, 15, 16

Answer 1

mean is 29.78

median is 16

Explanation:

Mean== add up all the numbers then divide by how many numbers you added up

So 268 divided by 9= 29.7777... rounded to 29.78

Median= put the numbers in order from least to greatest and mark off one from the low end then one from the high end until you find the middle. Since there are an odd amount of numbers, there will be exactly one left in the middle,
