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.

## Confidence Interval Calculator for the Mean (Known Population Standard Deviation)

Instructions: This calculator computes a confidence interval for the population mean $$\mu$$, in the case that the population standard deviation $$\sigma$$ is known. Please type the sample mean, the population standard deviation, the sample size and ...

## Minimum Sample Size Required Calculator – Estimating a Population Proportion

Instructions: This calculator finds the minimum sample size required to estimate a population proportion ($$p$$) within a specified margin of error. Please select type the the significance level ($$\alpha$$) and the required margin of error (E), ...

## 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 ...
