Online guide to working out statistics problems?

February 20, 2005 5:48 PM

I want to find a guide on the Web to help me work through statistics problems. Google finds plenty of terse definitions of terms, but not examples of how to solve equations.

Specifically I need to learn about exact values in cumulative distribution function tables. But where could I find something on the Web to take me through it?

Discrete or continuous? What kind of distribution?

Response by poster: Uh, semi-continuous. It's steps. Not completely discrete but it covers ranges.

Cumulative?

You're either doing:

• a sum of individual function calculations in the discrete case
• taking the integral of the function over a range in the continuous case

If you can indicate the kind of distribution, perhaps I can give you some tips.

Carnegie Mellon's OCI course might help you. But it seems like you just want a "tooltip".

The best math tutorial website I've found is Wolfram's Mathworld. (From the makers of Mathematica. Link is to the Statistics TOC)

maybe if you posted an example problem it would give people more idea of the kind of thing you're doing? i don't have a clue what you're talking about at the moment...
