This two-lesson plan is designed to teach grade 9 students how to create and interpret two-way frequency tables. The first lesson introduces the concept and structure of two-way frequency tables and how they summarize categorical data. The second lesson focuses on interpreting these tables to understand joint, marginal, and conditional relative frequencies, as well as recognizing associations and trends in the data, aligning with the Common Core standards for statistical understanding.
Lesson 1: Introduction to Two-Way Frequency Tables
Overview
In this lesson, students will be introduced to two-way frequency tables, a tool for organizing and summarizing categorical data. They will learn how to construct these tables, interpret the data they display, and explore the applications in finding associations and trends. Through a combination of explanation, collaborative activities, and discussion, students will develop the skills to utilize two-way frequency tables in analyzing data effectively.
Lesson 2: Interpreting Two-Way Frequency Tables
Overview
This lesson focuses on teaching students how to interpret two-way frequency tables to identify potential associations, trends, and relationships in categorical data. Students will learn to assess joint, marginal, and conditional relative frequencies and use them to draw meaningful conclusions from the data presented in the tables.
