1. TYPES OF GRAPHS

2. Vertical Bar Graph There are 4 main types of bar graphs.
The greater the length or height of the bar, the greater the value.

3. Horizontal Bar Graph
Bar graphs are usually used to compare numerical and categorical data.

4. Double or Group Bar Graph

5. Stacked Bar Graph
Stacked bar graphs can show segments of totals, but they are very rarely used.

6. Pictograph
Pictographs use picture symbols to represent statistical data.

7. Circle Graph/Pie Chart
Each segment in this type of graph represents a different category. The size of each segment is proportional to its value.

8. Line Graph
Line graphs compare two variables and are the most popular type of graphs because they are easy to read and create.

9. Multiple Line Graph
Multiple line graphs compare similar items over the same period of time.
