TLF ID L2380
Test a coloured spinner (dial with pointer) with three equal-sized sectors. Use a tool to build more spinners. Choose up to twelve equal-sized sectors. Choose one of three colours for each part of a spinner. For example, make a three-colour spinner with six red sectors, four yellow sectors and two orange sectors. Test the spinner over a number of spins. See which colour the pointer lands on each time. Watch the graph build after each spin. Compare the actual results with the expected results. Check whether increasing the proportion of a colour on a spinner increases the chances of the spinner landing on that colour.
