Outline of Activities: This activity let you experience how good sample statistics can be as estimates of the population parameters. Do we really have to study the entire population to find the TRUE value of the parameter? Are sample statistics good enough as estimates of the population parameters? How sample sizes affect these estimates? You will experience and get the answers to all these questions.
