TLF ID L2382
Look at results in a frequency graph compiled after testing an unseen spinner. Work out the likely proportions of colours in the mystery spinner. Use a tool to build a new spinner (a dial with a pointer). Choose up to twelve equal-sized sectors. Fill the sectors with up to five colours. 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 last in a series of three objects that progressively increase in difficulty.
