2. Definition
It is a measure that tells us where the middle of a bunch of data lies. The four most common measures are mean, median, mode and range
You would use this display when you want to find the over all average of a bunch of data

3. Example
Mean- Students height in a class Median- Test scores for a group of students Mode- Finding the most common hair color in the room

4. Data
The data required to make a graph is the mean, mode, median, and range
Numerical data set

5. Constructed Example
0,0,0,0,0,1,1,1,1,1,1,1,1,1,2,2,3,3,3,3,15
Mean- 1.9
You find mean by adding up all the numbers and dividing it by the amount of numbers there are
Mode- 1
You find the mode by finding the number that occurs the most
Median- 1
You find the median by finding the middle number (it needs to be in numerical order)
Range- 15
You find this by subtracting the smallest number from the greatest number
If 4 more zeros were added to the data what would happen to the mode?

6. Advantages and Disadvantages Advantages:
It neatly organizes the data in numerical order
It shows the mean, median, mode, and range
Disadvantages:
You cant use single, multiple, and categorical sets of data.
It can sometimes be misleading or not be exact
