A researcher is testing the effects of a new drug for improving memory. She tests a group of people with a high dose of the medication, another group is given a low dose of the medication, and a control group receives no medication. At the end of 3 months, she tests all three groups' memory.

Below are the memory scores for the three groups.

60 71 80
