The T-test allows you to compare two groups of samples and determine if the differences between them are more likely to be due to random chance, or whether they could indicate a causal relationship or a correlation.

Our calculator allows you to run this test on your own data by pasting it into the table. You can also run the test on the example data first, to see how it works.

It also gives you a graphical visualization of your data so you can see how the result of the test relates to your own judgement.
