[BlindMath] Statistical formulas

[The Euclidian]

Hi,

I will be going to sit for an exam in quantitative research within the
next week. While we are allowed to bring in calculators and formula
tables, I would solely rely on the provided computer where I would be
entering my answers. Since it is not mine but the one provided by the
institution with Jaws already loaded on it, I am wondering if there are
ways that I can enter statistics formulas in Word. I had been used to
working on my computer where I do everything in LaTeX and typeset it as
a PDF document, but for a computer without LaTeX on it, how best can I
deal with formulas?

Another thing that I am also asking help on regards these formula
tables: do you know of any accessible site on statistics where formulas
are presented in text or at least mathML rather than graphics? I am
especially looking at tweaking my skills on calculating formulas on
grouped data. For ungrouped data, I had often found help by going
through some R tutorials, but I never came across how to work with
grouped data. Any help would be greatly appreciated.
