    Collect some categorical data on a topic of interest to you and represent it in a statistical picture. Explain what you have done to make sure the picture is as useful as possible.

    A topic of interest to me is the Relationship between Exam Time and Exam Scores in an Online Intermediate Algebra Course. I feel that 1 hour is sufficient instead of 2 hours. I would represent the data in a scatter plot, with tables showing the data with respect to time versus score. The data would be split into 60 minutes versus 120 minutes on the y-axis, and the number score on the x-axis. The scores would be the raw scores out of a 25-question exam. Then, I would place in the best-fit line.
