Question

A researcher would like to determine if relaxation training will affect the number of headaches for chronic headache sufferers. For a week prior to training, each participant records the number of headaches suffered. Participants then receive relaxation training and for the week following training the number of headaches is again measured. Use SPSS to run a paired t-test and show all the steps involved in hypothesis testing as shown in the sample solution.
