[Blindmath] Statistics

Here's a link to a dropbox folder with BRF Z, T, and F tables. I recommend
using a BrailleNote or electronic note-taker of sorts with the ability to
search and find. I made the tables into lists more easily navicable than the
wide, many-colomn and row tables that wouldn't fit on any kind of Braille
display. 

Hope this helps.

I think the tactile ones only work for people who used to be cited in less
they are very simple. I can't read my professors notes because they were
written on a piece of paper and then posted to the website as a picture. I
can't read handwriting.

quantile given a probability, use =NORM.INV(0.9500,0,1) instead. Note I've
used mean=0 and sd=1 so that I have a standard normal distribution.

what we are trying to show our sighted audience. I'm far from convinced that
tactile images can be used to give a blind person enough information to
reliably answer questions that sighted people take for granted when they are
able to read a printed graph. On my to-do list is a set of what I hope will
be good tactile images. I want them in a form that is suitable for embossing
on decent embossers, and I'm also wanting to go 3d as well.
