A one-sample t-test, or single-sample test, is used to compare a samplemeanto a population mean when the null hypothesis is that the sample mean is equal to the population mean. Those who first encounter this test often wonder why they would use it, since the population mean is often ...

In a two-sample t-test, we can compare the mean of two different groups. These two groups can either be related or different from each other. For example, we can use it to compare which sports are the most watched in the US. The formula for the two-sample t-test is as follows: H...
