Is it a reasonable alternative?

I will recommend other software in some circumstances (usually if it is the right software being used by the class and adequate support is available). I seem to have missed my tenth anniversary for doing so on this list somehow.

I suggest that using any other software will mean you will have to rely much more heavily on sighted assistance.

As part of the preparation for that meeting, I recommend that all of you take a read of two articles written by me and the only other totally blind person to gain employment as a lecturer in a statistics department.

> 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
