Non-parametric Sign Tests

I've put together a calculator that performs the sign test for a small or large sample size population that will determine whether to accept or reject a null hypothesis based on a mean value

For the small population, the program will tie back to the binomial distribution calculator and for the large sample population, the program will use the normal approximation to the binomial distribution.

At this time, the program handles 1 number set, but later this month, I'll either add the capabaility to do a dual test, or design another lesson that does the dual test, i.e., T+ and T-.

It's located on the statistics page, and it is searchable by parametric, accept, reject, and hypothesis. Let me know if you want enhancements or see errors. Calculator instructions are at the top of the lesson.
