IB Assessment: Decimal Madness Data Analysis
Assessment of Criteria A: Knowledge and Understanding
Today, you will use your class’ test scores to display your knowledge of data analysis. Using
the “Decimal Madness Test Scores” printed on back, complete all sections of this assessment
below. Please neatly write your graphs and answers to numbers 3, 4, and 5 on a separate
sheet of paper that is stapled to the back of this one.
1. What is the mean grade of our class? _________________
(you may use a calculator for this one)
2. What is the median grade of our class? ________________
(show your work for this on the separate sheet of paper)
3. Create a frequency table and histogram to display our class test data.
(Do this on a separate sheet. Don’t forget to have the labels of “intervals” and
“frequency” in the table and on the X and Y axes of your histogram. Look back in your
notes or online if you’ve forgotten how to create a frequency table and histogram.)
4. Create a box plot to display our class test data.
(Do this on a separate sheet. Fill in the 5 number summary table below and use that to
create your box plot. Look back in your notes or online if you’ve forgotten something.)

5. On the separate sheet of paper, write a couple of sentences comparing your score on
the Decimal Madness test to the class average. Where does your score fall in
comparison? Are you pleased with your score? If you could re-do the Decimal Madness
week, in terms of your work ethic both in and out of class, would you do anything
differently? Please explain in detail.
