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.

T-test for two Means – Unknown Population Standard Deviations

Instructions: This calculator conducts a t-test for two population means ($$\mu_1$$ and $$\mu_2$$), with unknown population standard deviations. This test apply when you have two-independent samples, and the population standard deviations ...

Correlation Coefficient Calculator

Instructions: You can use this tool to compute Pearson's correlation coefficient for two variables X and Y. All you have to do is type your X and Y data, either in comma or space separated format (For example: "2, 3, 4, 5", or "3 4 5 6 7"). X data ...

Normal Probability Calculator

Instructions: This Normal Probability Calculator will compute normal distribution probabilities using the form below, and it also can be used as a normal distribution graph generator. Please type the population mean and population standard ...

Uniform Probability Calculator

Instructions: Compute uniform distribution probabilities using the solver below. Please type the lower limit $$a$$, the upper limit $$b$$, and define the event for which you want to compute the probability for: Lower (a) Upper (b) Two-Tailed: ≤ X ...

Correlation Coefficient Significance

Instructions: Enter the sample correlation $$r$$, sample size $$n$$ and the significance level $$\alpha$$, and the solver will test whether or not the correlation coefficient is significantly different from zero using the critical correlation ...

Odds Ratio Calculator

Instructions: This calculator computes the Odds Ratio (OR) for a 2x2 crosstabulation, which measures the ratio of the odds of exhibiting a condition (or disease) for those in an exposed group, versus the the odds of exhibiting the condition (or ...
