Problem Set 2: The paired-samples t test
Research Scenario: A psychologist is studying the efficacy of a new treatment program on the number of drinks per week reported in a sample of 10 males seeking help for alcohol abuse. She surveys the participants before the program begins and records the number of self-reported drinks per week. After two months in the program, the participants are surveyed again. The data are listed in the table below. Using this table, enter the data into a new SPSS data file and run a paired-samples t test to test the claim that the new treatment program significantly decreases the number of drinks per week.
The steps of the test will be the same as the ones you have been practicing in Part One of the assignment—the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the “Variable View,” then return to the “Data View” to enter and analyze the data.
