MATH FORUM PROBLEMS OF THE WEEK (POWS)
http://mathforum.org/pow/
After a summer hiatus, the Math Forum's Problems of the Week,
designed to provide creative, non-routine challenges for
students in grades 3-12, have resumed for the 1999-2000
school year.
This year we will be hosting six problems:
- Elementary
- Middle School
- Geometry
- Algebra
- Discrete Math
- Trig & Calculus
As our project grows, we need more adult mentors to reply
to students. Please consider joining our volunteer cavalry
mentor group, whose members send replies to a few students
each week. For more information, choose a level or topic and
follow its Mentor Project link; to read about how students
can participate, follow the link to a Current Problem, then
select Information and Guidelines, or Rules, or Frequently
Asked Questions.

t-test, Fisher exact, two by two table, ordinal tests,
pairwise
- discrete distributions: Poisson, binomial, hypergeometric,
negative binomial
- calculations: Bonferroni, random numbers, response rates,
sample size, significance testing, simple, power
Help documentation, MS-DOS programs, free life table
spreadsheets, conference listings, literature (Medline)

VisAble LARGE DISPLAY SCIENTIFIC CALCULATOR
http://www.betacom.com/bcVisLVpg.html
A calculator designed by the University of Waterloo's Centre
for Sight Enhancement that allows low-visioned users to
perform scientific, statistical, and trigonometric
calculations. Focus groups were used to determine the
functionality and visibility requisites for each feature of
the calculator, including its display, keypad, and
instruction manual. Includes all basic scientific and
mathematical functions.
