• Understand that mean, median, mode, range, and standard deviation are common statistics.
• Understand that each item/subject in a random sample has the same chance of being selected.
• Understand that generalizations are only valid if they are based on similar characteristics in both the sample and the population.
• Understand that decisions about the population can be made based on the information gathered from the random sample.
