MathCracker offers a wide variety of Statistics calculators, that will perform step-by-step calculations for you. Such calculators come in all forms and shapes, some are very simple (such as for example, simple combinatorial coefficient calculations) and some conduct elaborate calculations (such as some non-parametric statistical test).

One great advantage of our online calculators/solvers is that we attempt to provide, whenever possible, a complete step-by-step detail of how to arrive to the required solution. We believe that showing all the steps of how one has arrived to the solution is the best way (and sometimes the only way) to learn a subject.

There are many probability calculators (including calculators for the most common distributions, such as the normal, the t-distribution, the F-distribution, etc), a complete selection of hypothesis test solvers, for both parametric and non-parametric tests.

## How to Find the Stats Calculator I'm looking For?

Check our list below of Stats solvers, or you can also use the search box provided, to find the exact calculator you are looking for. Each solver will come with clear instructions on how the solver should be used. Also, some calculators will have available videos that will help you to proceed if you are having troubles.

Our goal is to have the most complete collection of math calculators online, and when I say Math I mean that we don't only have stats calculators but also Algebra, Probability, and many other subjects. If there is a solver that you don't find in our site and you would like to see included here, please do not hesitate to contact us.
