Students to identify the target population in examples of experiments on a sheet. Students divide up into four groups and each group takes a different sampling technique. They research their method and find out what the strengths and weaknesses of their method are. Students then present their method to the rest of the class, and the class adds each method to a summary mind map. In pairs, students decide which sampling method will be used in their investigation into music and memory. Present students with scientific findings that have been generated a range of sampling techniques and encourage them to evaluate each example. Include examples of poor sampling strategies. Students are placed in teams and complete a quiz into identifying the target population, sampling method and the advantages and disadvantages of different methods.
