Testing and Analyzing
a Six-Sided Die
Models are three-dimensional designs that can be used to display, observe, or test a design. In the
“Principal Planes of a Six-Sided Die” activity you investigated the principal planes by creating a
model of a six-sided die. Now you are going to test and analyze your model.
Create a table that lists each principal plane. Roll your model 100 times and record which plane is in
the up position for each throw.
Answer the following questions in complete thoughts and sentences:
1. What should the ratio (number of times each principal plane lands in the up position) of
six-sided die throws out of 100 look like if your model is truly random?
2. What was your actual ratio of die throws?

3. What accounts for the discrepancy?
4. Using your own data, create a bar graph or pie chart on paper or in a spreadsheet application.
Make your principal plane the X-axis or a color-coded key. The number of times each principal
plane came up should be your Y-axis for a bar graph. As an alternative, you could convert to
percentages to create sections of a pie chart.
5. Compare your data with three other students. Describe the trends and discuss the possible
reasons for any discrepancies.
