In this page you will all the T-tests we have available. Check the list below:

## 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 ...

## 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 ...

## 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 ...
