U.S. Census Bureau: Statistics in Schools

The U.S. Census Bureau unveiled its newly updated Statistics in Schools program for K-12 teachers and students earlier this month. Using current and historical data, the Census Bureau program provides teachers the tools to help students understand statistical concepts and improve their data analysis skills. There are free online activities and other resources available in geography, history, social studies, sociology, as well as math.

It looks good.

Statistical Questions

What makes a question a statistical question? Furthermore, what makes a good statistical question?

The Common Core State Standards (6.SP.A.1) describes it like this:

... one that anticipates variability in the data related to the question and accounts for it in the answers. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages.

This statistics standard is slated for 6th grade students¹, but I recently heard a more effective explanation of what a statistical question is that will be relevant for middle school, high school, and college statistics. It also defines what makes a statistical question a good one, which the Common Core definition does not.
