Step 6 Objective
Estimate probabilities from experimental data; understand that:
- if an experiment is repeated, there will be different outcomes;
- increasing the number of times an experiment is repeated generally leads to better estimates of probability.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
What if pupils find this a barrier?
Carry out an experiment, e.g. coloured counters taken from a bag. Do the experiment twice to demonstrate the difference in the results but take out a counter as many as fifty times in each experiment to demonstrate similarities.
Use the results to give experimental probabilities. Indicate these on a 0 to 1 line.
