06 Paired Samples t-Tests in SPSS – SPSS for Beginners

You use a paired samples t test in two research designs. One, you conduct a study with a before-and-after design, in which you measure the same sample at two different times with a treatment in between. Two, you have paired participants, such as a study of twin pairs, matched samples, or even puppy siblings from the same litters (see the extended video below). This test is variously called “repeated measures t test,” “repeated t test,” “paired t test,” or “paired samples t test.” All of them use the “within subjects” design. In this video, you will also learn about how to interpret the output of this test.

The presenter is the typical presenter whom I expect to watch. He precisely explained the topic. He used time effectively - only important points are explained without boring.
