In Study 2 of Blackwell et al. (2007), students were randomly assigned to two groups. Both groups attended an eight-week workshop, but only the intervention group was taught that learning changes the brain. After the workshop, the intervention group achieved significantly higher maths scores than the control group.
Explain how comparing the two groups in this way strengthens the researchers' conclusion from Study 2.
