# Ch 2: Common Core HS Statistics & Probability: Categorical Data

Use our high school statistics and probability video lessons. Prepare your students to meet the common core standards for performing statistical analyses with categorical data.

Standard: Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data. (CCSS.Math.Content.HSS-ID.B.5)

Students who have mastered this standard are able to perform statistical analyses using categorical data. While completing these analyses, students will employ frequency tables, pie charts and bar graphs.

The lessons in this standard cover the following topics:

• Categorical data used for statistical analysis
• Tables for summarizing categorical data
• Pie charts and bar graphs
• Frequency and relative frequency tables

Students demonstrate mastery of this standard when they make effective use of bar graphs and pie charts to analyze categorical data, in addition to using relative and cumulative frequency tables to calculate percent increase. This standard can prepare them for college courses that require an ability to comprehend research being performed in their major areas of study.

### How to Use These Lessons in Your Classroom

Here are some tips for incorporating these lessons into your curriculum to help meet the common core standards:

#### Tables Lessons

Have students watch the video lessons involving categorical data and tables. Gather information concerning those students in class who wear bicycle helmets and those who choose not to wear helmets. As a group, construct a table incorporating the data.

#### Bar Graphs and Pie Charts Lessons

After watching the video lessons about bar graphs and pie charts, use the data gleaned in the activity above to construct both a pie chart and a bar graph.

#### Relative Frequency Lessons

Share the video lessons concerned with relative frequency. In small groups, ask students to share whether brand names are important to them when they go shopping for clothing. Each group will then construct a relative frequency table and a bar graph using the data.
