This document provides information about different types of graphs. It defines what a graph is as a two-dimensional drawing that shows the relationship between two sets of numbers using a line, curve, bars, or other symbols. It then describes several common types of graphs: circle graphs that display data in circular sections; bar graphs that use vertical or horizontal bars of equal width; pictographs that use pictures and symbols with a key; broken line graphs that join data points over time with line segments; continuous line graphs where points on the line also have meaning; and scatter plots that show a set of plotted points.

- 2. What is Graph Two-dimensional drawing showing a relationship (usually between two set of numbers) by means of a line, curve, a series of bars, or other symbols. Typically, an independent variable is represented on the horizontal line (X-axis) and an dependent variable on the vertical line (Y-axis). The perpendicular axis intersect at a point called origin, and are calibrated in the units of the quantities represented. Though a graph usually has four quadrants representing the positive and negative values of the variables, usually only the north-east quadrant is shown when the negative values do not exist or are of no interest.
- 3. Types of Graph Circle Graph Displays data using a circle divided into sectors. We use a circle graph to show how data represent portions of one whole or one group.
- 4. Bar Graph Displays data by using bars of equal width on a grid. The bars may be vertical or horizontal. What do you think the graphs are representing?
- 5. Pictograph Uses pictures and symbols to display data; each picture or symbol can represent more than one object; a key tells what each picture represents.
- 6. Broken Line Graph A graph showing data points joined by line segments to show trends over time.
- 7. Continuous Line Graph A graph in which points on the line between the plotted points also have meaning.
- 8. Scatter Plots A graph of data that is a set of points.
