### Other Types of Graphs

2-3

Other Types of Graphs
• In addition to the histogram, the frequency polygon, and the ogive, several other types of graphs are often used in statistics. They are the bar graph, Pareto chart, time series graph, and pie chart.
Bar graphs

When data is qualitative or categorical, bar graphs can be used to represent the data. It can be drawn using either horizontal or vertical bars.

Pareto Charts

When the variable on the horizontal axis is qualitative or categorical, a Pareto chart can also be used to represent data.

Time Series Graphs
• When data are collected over a period of time, they can be represented by a time series graph. When you analyze a time series graph look for trend or pattern that occurs over the time period.
The Pie Graph
• Pie graphs are used extensively in statistics. The purpose of the pie chart is to show the relationship of the parts to the whole. A pie graph is a circle that is divided into sections or wedges according to the percentage of frequency
