What if my data isn t nearly normally distributed. For example you can use this test to assess whether there are mean differences when the same group of people have been assessed twice such as when determining if an intervention had an impact by using a before and after design. To conduct a paired t test we can use the following approach.
Let a the student s score on the first test and b.

The paired samples t test is a statistical test used to determine if 2 paired groups are significantly different from each other on your variable of interest.
