6. Box Plot (Box &Whisker)
A plot showing the minimum, maximum, first quartile, median, and third quartile of a data set; the middle 50% of the data is indicated by a box. Example:

7. Box Plot: Pros and Cons Advantages: Shows 5-point summary and outliers
Easily compares two or more data sets
Handles extremely large data sets easily
Disadvantages:
Not as visually appealing as other graphs
Exact values not retained

8. Dot Plot
A frequency plot that shows the number of times a response occurred in a data set, where each data value is represented by a dot.
Example:

9. Dot Plot: Pros and Cons Advantages: Simple to make
Shows each individual data point
Disadvantages:
Can be time consuming with lots of data points to make
Have to count to get exact total. Fractions of units are hard to display.

10. Histogram
A frequency plot that shows the number of times a response or range of responses occurred in a data set.
Example:

11. Histogram: Pros and Cons
Advantages:
Visually strong
Good for determining the shape of the data
Disadvantages:
Cannot read exact values because data is grouped into categories
More difficult to compare two data sets

12. Bar Graph
A graph that displays relative data sizes of many things with vertical or horizontal bars. Example:

13. Bar Graph: Pros and Cons
Advantages:
Display data that can be organized into categories
Can quickly compare the categories
Disadvantages:
Having continuous data (such as a person's height) then use a Histogram

14. Double Bar Graph
A graph can be used to compare two data sets. Example:

15. Double Bar Graph: Pros and Cons
Advantages:
key to distinguish between the two sets of data
Disadvantages:
Having continuous data (such as a person's age) then use a Histogram

16. Line Graph
A graph displays data using line segments that shows information that is connected in some way (such as change over time).
Example:

17. Line Graph: Pros and Cons
Advantages:
A broken scale can be used when the data starts at a large number. 
Show specific values of data, so if you are given one variable the other can easily be determined
Disadvantages:
It can only be used to show data over time
You can change the way the data of a line graph appears, by not using consistent scales on the axis.

18. Double Line Graph
A graph that can be used to compare how two related data sets change over time.
Example:

19. Double Line Graph: Pros and Cons
Advantages:
key to distinguish between the two sets of data
Disadvantages:
Having continuous data (such as a person's age) then use a Histogram

20. Circle Graph
A graph that shows part of a whole. The entire circle represents 100% of the data and each sector represents a percent of the total.
Example:

21. Histogram: Pros and Cons
Advantages:
Visually strong
Good for comparing each category of data to the whole set
Helpful to illustrate profits as they use percentages
Disadvantages:
Two data sets cannot be compared and percentages do not provide exact figures
