## Analyzing Country Data

#### Activity Overview

In this activity, students will examine sample ages from three countries displayed in a spreadsheet and in relative frequency histograms that highlight the distinctive features of the distribution of the ages from each sample.

#### Objectives

• Students will determine and interpret percents to summarize data.
• Students will interpret medians and quartiles to summarize sample data. Use measures of center and measures of variability to draw informal comparative inferences about two populations.
• Students will compare and contrast different sample data summarized by box plots and histograms. They will assess the degree of visual overlap of two numerical data distributions.
• Students will construct viable arguments and critique the reasoning of others.
• Students will use appropriate tools strategically.
