http://www.ck12.org Chapter 8. Organizing and Displaying Data for Comparison
8.1 Basic Graph Types
Here you’ll learn how to organize and describe distributions of data by using a number of different methods,
including frequency tables, histograms, standard line and bar graphs, stem-and-leaf displays, scatter plots, and box-
and-whisker plots.
What’s the difference between discrete data and continuous data? Would a collection of temperatures be discrete
data or continuous data? What’s the difference between qualitative and quantitative data? Are test scores quantitative
or qualitative? Would data concerning eye color be quantitative or qualitative?

Guidance
In previous Concepts, you learned about discrete and continuous data and were introduced to categorical and
numerical forms of displaying data. In later Concepts, you will learn how to display discrete and continuous data in
both categorical and numerical displays, but in a way that allows you to compare sets of data. However, as a review,
let’s first go through the following examples.
Example A
Which of the following graphs represents discrete data? Which represents continuous data?
