Kendrick wants to know whether creative activities, such as knitting, improve students’ ability to cope with academic stress. He randomly assigns every other student in the “knitting condition” and asks them to spend 2 hours per week knitting. He puts the other students in the “control condition” and asks them to spend 2 hours per week reading a book about knitting. Later, he asks them to report how stressed they feel about school.
