Sampling –


Sampling involves selecting a representative group of people from a population. Let's say you wanted to survey a fifth-grade class about what they would like to do for a service project. Suppose you only talked to the five people sitting together in the back of the room who are friends with each other. Their opinions might all be very similar and they might all say the same thing. To avoid bias in your survey - try to ask a representative group to take the survey. Instead of asking just the five students at the back of the room, pick students randomly from around the room.



Picking people at random to take a survey is known as simple random sampling. There are many other sampling techniques used by professional researchers, including stratified sampling, multistage sampling and cluster sampling.
