Penny,

Check out John Gardner's Accessible Graphing Calculator -- it has many
stastical functions.  I actually got by fairly well with Excel, but you
have to install the data analysis tools (it is somewhere within Excel, but
it was over a year ago, so I don't remember exactly where or how to do it).

Other things that would help would be some tactile graphics to show what a
normal distribution looks like, where the p and standard deviation points
are, and what a skewed distribution looks like.  Also, tactile diagrams of
other kinds of plots such as a box plot may also be useful depending upon
the student and the way the course is taught.  These days, a good
statistics course focuses mostly on concepts and principles rather than
mathematics (let the computer or calculator do the repetitive drudgery, and
forget things like statistical tables)  It is far more important to
understand what you are doing and why then to be able to do lots of number
crunching).

Hope this helps,

Jim
