APR Tuesday Tip: Quota Sample

Many people confuse this for a random sample, but it's not. It may be representative of your total population, but it's not random and can't be projected onto the entire group.

Front: Quota Sample

Back: A nonprobability sample. Ex. In a school, find 10 elementary teachers, 10 middle school teachers, and 10 high school teachers. Any 10 of each kind.
