Mrs. O'Grady wants to know if doing Tabs with her science class really helps them learn the material better. She decides to test this out in her two 10th grade science classes. In both
classes she gives the same amount and type of notes and homework, but in one class she
does labs and the other class she does no labs. At the end of the unit, she gives both classes
the same unit test and compares the class averages. The group that did labs scored 15 points
higher on the test.
