Episode Details

This lesson describes how statisticians are best able to accurately describe a population by taking a proper sample. Whether it’s examining a small piece of coral reef to determine the state of miles of ocean floor life or polling the right voters to determine how a candidate’s religion or race will affect their popularity, statisticians have to sample properly to get an accurate picture of the larger population. In this lesson you will learn the rules that must be followed to sample properly. You will also learn how a truly random sample can be generated to ensure that a sample really does represent the entire population.
