Skew The Script lessons identify misleading data arguments and show students how the tools of statistics can be used to gain a deeper understanding of some of our country’s longstanding problems. Even more important, the lessons provide students from widely differing backgrounds with a common analytical lens (rigorous data analysis) for heightened discourse around social issues.
There are many concepts associated with hypothesis testing, but it all comes down to variation. How unusual is the variation we observe in a sample?
Students can often lose sight of this basic idea once they have learned the various procedures introduced in an introductory statistics course. Further, they may blindly follow the procedure and never question the impact of the sample size or magnitude of variation on the conclusion they draw.
In this lesson by Douglas Whitaker, students explore nonlinear regression models to explain fish weight by using fish length. They will use both transformation of the response variable and polynomial regression.
A roundup of statistics and education-related information and opportunities
When 2020 pitched its curveball at educators, one of the largest challenges we faced was finding equitable, meaningful assessments that could be delivered remotely. In other words, could we write exam questions we thought students would find authentic and still allow us to feel confident we were learning about students’ individual achievements?
The Sampling Bag Task showcases important statistical ideas, encourages conjecture and statistical argument, and illustrates the complexity and promise of seemingly simple tasks to generate productive discourse and expand understanding of statistical ideas.
The ability to read, write, and evaluate statistical arguments are crucial to the development of statistical literacy. Here are some tools for facilitating that development.
A roundup of statistics and education-related information and opportunities.
In this lesson, each student tries two methods for selecting a sample from the population of words in the Gettysburg Address: self-selection and simple random sampling.
In this lesson from Christine Franklin, Gary Kader, Tim Jacobbe, and Kaycie Maddox, students investigate how to interpret the mean using fair share value and the balance point of a distribution.
