• WELCOME TO MATH!

Today we will work further with median and mean.
Yesterday we worked with an odd number of items in a set of data when we were trying to figure out the median. Soon it became pretty clear as we crossed off numbers that the remaining number in the middle was the median.

But what if the number of items in the set of data is an even number?
Hmmmmm .....

NOTE:  If there is an even number of items in the set of data, the median is the average of the two middle numbers.

Given the above information, here is your Challenge:

FIND THE MEDIAN.  1, 2, 3, 4, 8, 9, 10, 11

First, cross off a number from each end of the set.
Continue until you are down to just two numbers. (You will have Two numbers because the set
contains an even number of items.)
To find the average of the two middle numbers, add them together and divide by two (the number of items remaining).
So your math sentences will look like this:    4 + 8 = 12  and  12 ÷ 2 = 6
The median is 6.
