The goal of this page is to post interactive graphs that can be used as a classroom resource. Over time, the hope is to add questions that can be used as assignments. In the meantime, consider using these graphs as part of course assignments and let me know if they have been helpful, how to improve them, and what you would like to see. Cheers, Tom

### Median Wages by Race and Gender

Data from EPI and available in Statistics Projects. Click on the graph for an interactive chart. Clicking on the legend elements hides the corresponding graph element.

### Mean Wages by Race and Gender

### Life Expectancy by Race and Gender

Data from the CDC (2015 data from 2018 report). Click on the graph for an interactive chart. Clicking on the legend elements hides the corresponding graph element. Consider compare data on hover as points are close to each other and hard to isolate. Regression lines are from age 5 to 70. Questions: What does the slope of the line mean in this context? Is there anything interesting in the residual plots? Related paper: Period Life Tables: A Resource for Quantitative Literacy by Pfaff and Seltzer.
