TLF ID L2381
Predict the results of testing coloured spinners (dials with pointers). Choose two spinners that are likely to generate similar results. For example, choose a four-part spinner with two blue sectors and two yellow sectors. Match it with an equivalent spinner divided into blue and yellow halves. Test the pair of spinners over a number of spins. See what colour the pointer lands on each time. Watch the graph build and the numbers in the results table change after each spin. Compare the actual results with the expected results. Check whether spinners with the same proportion of each colour produce similar frequency graphs. This learning object is one in a series of six objects.
