T-test for paired samples

Video: T-test for difference of two means in paired samples

When we test for the difference of two means, it makes a difference whether the samples are paired or independent. In this video Dr Nic undertakes a hypothesis test on the difference of two means in paired samples.

To find out more about the difference between paired samples and independent samples, and for a description of the two examples, see the video Paired and independent samples

To find out how to test for independent samples see the videos Hypothesis Test – t-test for difference of two means and Two means t-test in Excel.
