Teacher Resources

In this module, the students summarize categorical data for two categories in two-way frequency tables. They interpret relative frequencies in the context of the data (inlcuding joint frequency, marginal frequency, and conditional relative frequency). The students will recognize possible associations and trends in the data. This self-paced module is aligned with the Maryland College- and Career-Ready Standards in Mathematics for Algebra 1, which are based on the Common Core State Standards (CCSS).

This module contains several interactive features. Watch the Learn How to Use this Module tutorial to familiarize yourself with these features.

Please review the Accessibility page for all of your students.
