[BlindMath] Scatter Plots for Regression Analysis

[Susan Osterhaus]

The Orion TI-84+ from APH and Orbit Research's collaboration can do
regression analysis. Our high school students use this accessible
calculator for such tasks. However, we are able to obtain these
calculators for our students with federal quota monies, and therefore it
is an affordable user-friendly method. I believe Jonathan Godfrey (also a
member of this list) is the expert on using the R statistical software,
which might interest you.

Subject: [BlindMath] Scatter Plots for Regression Analysis

Hi,

Apologies for bringing up a topic that must have been covered before, but
the lack of a search functionality in the list archives makes it unuseable
for referring to past discussions on a specific topic.

I'm taking a course on regression analysis, and my professor said that "
There are quite a number of plots throughout the course as scatter plots
are very important parts in finding an appropriate model, a suitable
transformation and in checking for assumption based on the residuals."

Does anyone have ideas on how to deal with these or possible alternatives
for assessment purposes?

Thanks
