Chapters begin with new, motivating examples and follow through with analyses of the data then, real-world examples provide a basis for sample problems and exercises. With the deemphasis on the computational aspect of the regression model, it allows time to have students answer some questions to help facilitate their understanding. World 3rd Edition Answer Key Stats: Modeling the World by Bock, Velleman, DeVeaux, and Bullard engages students by opening with practical data analysis and graphics. Even more importantly, the output from the Desmos worksheet allows students to find the calculated values easily. I think the ability of the Desmos worksheet to help animate points in the plane is a powerful use of the technology. The Desmos sliders make it easy to change the wandering point to the suggested points as well as any others that a student desires to help them explore the questions. If you are familiar with the original activity, you'll perhaps notice some of the other changes I made. They, as well as a colleague or two, made some nice constructive suggestions (for example, estimating what kind of leverage each wandering point has) and I have included those as well. I field tested this today and got an overall positive review from my students.
To be used with the Desmos interactive worksheet: The Wandering Point, Updated Student worksheet for my updated activity: The Wandering Point, Updated
The students are asked to use the Desmos interactive worksheet to find the correlation and slope of the LSRL as well as make an estimate of the residual and leverage for each possible fifth wandering point. Inspired by the 2016 GAISE Report revision, Stats: Data and Models, 5th Edition by De Veaux, Velleman, and Bock uses innovative strategies to help students think critically about data, while maintaining the book’s core concepts, coverage, and most importantly. I left the original idea of the four points as well as the requested changes to the fifth point. Encourages statistical thinking using technology, innovative methods, and a sense of humor.

"The Wandering Point" activity essentially has students explore the changes to the linear regression model and correlation when a fifth "wandering" point is added to a set of four fixed points. Intro stats 4th edition by de veaux velleman bock test bank.

I have since adapted* this activity to incorporate the new regression function of Desmos as well as some modifications to enhance student understanding. Solution Manual for Stats: Data and Models, Third Canadian Edition Plus MyLab Statistics with Pearson eText 3rd Edition By Richard D. My students always get a lot of out it and I think it lends itself to a high level of student engagement. Bock, Augustin M.One of my favorite activities from the Stats: Modeling the World teaching materials is "The Wandering Point" class activity to look at the influence of points on correlation and linear regression.
