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 One Population Mean

Instructions: This calculator conducts a t-test for one population mean ($$\sigma$$), with unknown population standard deviation ($$\sigma$$), for which reason the sample standard deviation (s) is used instead. Please select the null and alternative ...

Confidence Interval Calculator for the Mean (Unknown Pop. Standard Deviation)

Instructions: This calculator computes a confidence interval for the population mean $$\mu$$, in the case that the population standard deviation $$\sigma$$ is not known, and we use instead the sample standard deviation $$s$$. Please type the sample ...

Mean and Standard Deviation Calculator

Instructions: Enter the sample data below and the solver will provide step-by-step calculation of the sample mean, variance and standard deviation: Type the sample (comma or space separated) Name of the variable (Optional) More About Descriptive ...

T-test for Paired Samples

Instructions: This calculator conducts a t-test for two paired samples. This test applies when you have two samples that are dependent (paired or matched). Please select the null and alternative hypotheses, type the sample data and the significance ...

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), ...
