Big Ideas: Categorical data is data that can be sorted into separate groups based on a like-characteristic. Categorical data should be visually represented using a bar graph, pie chart, or segmented bar chart. This lesson builds on students’ previous work in 3rd grade with categorical graphs. The task will ask students to identify whether a data set is categorical in nature. They will then be asked to construct graphs to represent the categorical data sets. Students should note that one can use frequencies or relative frequencies to label the values in the graphs. It should also be noted that pie charts and segmented bar graphs enable readers to easily compare parts to the whole. Vocabulary: Univariate, Categorical, Frequency, Relative Frequency Special Materials: Civil War casualty Slips Chart paper for data collection and graphing OR guided data collection and graphing sheet. Markers (optional) Computers (optional - if you choose for students to make pie charts with technology) OR straightedge and protractor (optional - if you choose for students to draw pie charts by hand)
