[BlindMath] Scatter Plots for Regression Analysis

Thu Jan 11 04:04:22 UTC 2018

Back then, it was the only way.  No reasonable person would do it now when thee are much easier and efficient ways to do it.  I have seen many graduate regression classes have students do some for homework as a way of teaching it, but they also are shown how to do it with a program.  It is sort of like learning basic Calculus until they show you how to do it quickly with a formula.

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.
