Look at results in a frequency graph compiled after testing an unseen spinner. Work out the likely proportions of colors in the mystery spinner. Use a tool to build a new spinner (a dial with a pointer). Choose up to five equal-sized sectors. Fill the sectors with up to five colors. For example, make a six-part spinner with three red sectors, two blue sectors and one yellow sector. Test the new spinner over a number of spins. Look at a graph of the test results. Compare it to the graph generated by the mystery spinner. Are the results similar? This learning object is the second in a series of three objects that progressively increase in difficulty.
1. Students explore the difference between the information provided by short-run, medium-run and long-run data.
2. Students explore the relationship between sample space and likelihood of outcomes.
3. Students analyse experimental data to identify mathematical equivalence in random generators.
4. Students interpret data in tables and graphs.
