Strong Points: Basic calculations/analyses
Weak Points: Not a replacement for commercial products

I don’t know about you, but I’m not very strong on statistical analysis. I say that with a bit of a red face, because there is no really good excuse for a scientist to be deficient in this department. That said, I look for help in this area. One can go out and buy expensive products to do extraordinary whiz-bang statistics, moderately priced packages (including some by this site provider), and freebies, such as are found here. I’m a freebie kind of guy, so I checked out GraphPad’s QuickCalcs. What I found satisfied my basic needs, which included analysis of categorical and continuous data, simple statistical distributions, random number calculations, and some calculations for chemical and radiochemical analysis. Would these replace a commercial package? No, but cleverly, they may cause visitors to check out the offerings of the site’s provider.
