Review Topics for Success

Learning Outcomes

By the end of this section, you will be able to:

  • Read and interpret data from pie charts and bar charts as percents
  • Read and interpret data using two-way tables

In this module, you will study tests for qualitative or categorical data. In particular, you may want to determine whether the distribution of data is as expected, if two variables are independent, and if two population distributions are the same. In this section, we’ll review how data is represented graphically using pie charts and bar charts, and how two-way tables are used to represent data characterized by two attributes.

Recall for success

Look for red boxes like this one throughout the text. They’ll show up just in time to give helpful reminders of the math you’ll need, right where you’ll need it.
