Random Sampling

Sample pennies to gain an understanding of their ages. The 16th installment of a 25-part series requires groups to collect samples from a jar of pennies. Pupils compare the distribution of their samples with the distribution of the pennies in the jar. Groups also use random sampling to investigate the prices of groceries.
