Problem Set 1: The paired-samples t test
Research Scenario: A sports psychologist is studying the efficacy of a new public school health program on the number of minutes 10th graders exercise per week. She surveys a sample of 10th graders before the program begins and records the number of minutes they report exercising per week. After two months in the program, the students 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 health program significantly increases the number of minutes exercised per week. Follow the directions below the table to complete the homework.

Problem Set 2: The paired-samples t test
Research Scenario: A social psychologist is studying the differences in the number of Facebook® friends between identical twins raised apart. She believes that twins raised in different environments will have differences in the number of friends, which would help point to the influence of environmental factors over inherited factors on social outcomes. She divides the twins into two groups ("Twin 1" and "Twin 2"), collects the data and creates 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 identical twins raised apart will have a different number of Facebook® friends. Follow the directions below the table to complete the homework.
