A person is studying the relationship between temperature and mental ability. So, she devised a test in which a group of 10 mice are timed as they run through a maze
which leads to food and water. The researcher repeats the test 3 times with each
group to see how much they improve and she uses three groups.
• Group 'A', does the test under normal room temperature of 76°F.
• Group 'B', does the test in the cold at a temperature of 45°F.
• Group 'C', does the test under a hot temperature of 105°F.
How would you most correctly describe Group 'A' in a statistical study?
