O Bar graph O Pie graph Histogram Line graph Lighting Experiment A researcher wants to determine whether classroom lighting affects learning. To do this, she runs an experiment in which subjects are randomly assigned to receive a statistics lesson in a brightly lit room or a dimly lit room. In order to determine how much subjects learned, she asks all subjects to take a statistics test after their lesson. (Hint: This means test scores are the dependent variable and room lighting is the independent variable.) Her subjects' scores are listed below. Scores of subjects in the brightly lit room: 85, 90, 93, 99, 72, 83, 86, 72, 80 Scores of subjects in the dimly lit room: 82, 81, 88, 92, 94, 92, 73, 76 11 6 points What are the mean, median, and mode in each room?
