A frequent problem in personal science is that you tried an intervention and want to see if it worked. But you are unsure whether any differences you observed are maybe just by chance. So how can you see how likely is it that the results were chance? One of the simplest tests is a '''T-Test''', sometimes called a “Student T Test”<ref>https://en.wikipedia.org/wiki/Student%27s_t-test</ref>, which provides you with a ''p-value'' after doing the t-test.
