If a statistician seeks to know the answer to some question, he or she often can't possibly ask every single person he/she wishes to study. The population is the whole group that a statistician wants to describe, and the number he is looking for is called a parameter. Rather than asking every single person, they choose a sample (hopefully random and representative of the population) and gather a sample statistic that describes what we hope is the population parameter. The way in which a sample is chosen is very important for gathering an accurate sample statistic.
