Question

For the following questions, use 22, 24, 20, 18, 19, 18, 22, 25, 21. Round any decimal

numbers to the hundredths place.

1. Find the mean.


2. Find the median.

Answer 1

1. The mean is 21.

The can find the mean by adding all the numbers up in this case “18, 18, 19, 20, 21, 22, 22, 24, 25” and dividing it by how many numbers there were in total. (aka 9 in this set of numbers.) so, you would do 189 divided by 9 to get 21. (the mean is the arithmetic average.)

2. The median is 21.

to find the median you list the numbers from least to greatest, “18, 18, 19, 20, 21, 22, 22, 24, 25” count how many numbers there are in total (9) and then look for which number is in the middle (aka the 5th number) which was 21.
