Hi, Rianna.

The median is the middle value when the numbers are written in numerical order. This list is already in order, but you may have to rewrite some of your other homework problems. If there is an odd amount of numbers in the list, the median is the middle number. If there is an even amount of numbers (as in this case), you may have to find the average of the middle two. In this case, the two middle numbers were both 5, so your median is 5.

The mean is another word for the average, which you find by adding up the numbers and dividing by how many numbers there are.

The mean is the average of the numbers, which is the sum of the numbers divided by the numbers of numbers.  In this case, it is (4 + 5 + 5 + 5 + 11 + 25)/6 or 45/6 = 7 3/6 = 7 1/2

The median is the middle number if you put them in size order.  In this case, there are 6 numbers, so the average of the 3rd and 4th numbers is the median.  Since both numbers are 5, the median is 5

Hi Rianna,

Think of median being like a median when you drive.  When you drive a car, the section the middle that you can stay on is called the median.  Median = middle.

The middle number here is 5.  If there are even amount of numbers, then you take the 2 middle numbers, add them, and divide by 2.

Think of mean being what did you mean by that or what did you mean to do in most cases.  Mean = average of what it usually is.

To get a mean, you add up all the numbers.  Then, you count the number of digits.  You divide the addition by the number of digits.
