### Analyzing Country Data

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.

### Boxplots Introduction

This lesson involves representing distributions of data using boxplots.

### Center of Mass

Students will identify and interpret the mean geometrically as the location of the coins on the ruler such that the sum of the distances on either side of the mean is the same.
