Paired samples t-Test in SPSS - what is it and how to use it

The paired samples t-test is used when you have a dependent variable on an interval or ratio scale and want to test for a difference between two measurements for the same or paired individuals. ➡️ Watch next:    • Reporting Paired samples t-test - results ...   For example: =========== I have a measurement of pushups from 100 individuals before a four week long training. After the training, I will again measure the number of pushups the individuals are able to do. Formulated differently: Does the training lead to an increase in the number of repetitions for the individuals? Video contents: ============= I'll show how to conduct the paired samples t-test and interpret the results using IBM SPSS statistics. Your data needs to be in the wide-format for the analysis to work. This means that ech measurement has to be in a separate variable. In order to keep the video as short as possible, I won't test the requirement of approximately normally distributed residuals, see below for a video on that. The interval or ratio scale of the test variable is pretty obvious and does not need any testing. Testing the assumption of normal distribution for the residuals: =================================================== 🎥    • Paired samples t-Test in SPSS - checking n...   Calculating the required sample size: ============================== 🎥    • Paired t-Test - calculate required sample ...   📚 Sources: ========== Grissom, R.
