Product Description
How have Olympic swimming speeds changed over time? Are male and female swimmers getting faster at the same rate? Is a linear model a reasonable way to predict how fast future gold medalists will swim the 100-meter freestyle?

In "Swimming in Scatter Plots," students will construct and analyze scatter plots using 100 years of Olympic swimming data. Half the class will have data from the Men’s 100-meter freestyle, and the other half will have data from the Women’s 100-meter freestyle.

Then, pairing up students with different data sets, they will check each other’s work, compare the data sets, and answer thought-provoking questions about the reasonableness of the linear model.

Carefully structured, this set of tasks incrementally walks students through a comprehensive data analysis experience, and uses plenty of algebra along the way.

This flexible resource could be used for practice, cooperative learning, homework, or enrichment.

What's Included?

1. Teacher notes with ideas for implementation.
2. Two independent scatter plot tasks, one with men's swimming data and one with women's. (2 pages each).
3. Partner task (2 pages)
4. Detailed solutions, including completed scatter plots with lines of fit for both sets of data.
