Dr. Kaiser, a sports psychologist, wants to know if he can improve the cardiovascular endurance in elementary school children. He is allowed to study two physical education classes at a local school, one boys' class and one girls' class.
On the pretest, the girls on average have slightly better cardiovascular endurance as measured on the step test. He administers the year-long aerobic program to the girls' class. The posttests revealed that the girls' cardiovascular endurance improved much more than the boys.' Dr. Kaiser must now decide if the program really worked or
a. if there was a regression artifact.
b. if there was a selection-maturation effect.
c. if girls always do better in aerobic exercises.
d. if there was an attrition effect.
