Convenience sampling

Convenience sampling is when a researcher selects a research sample that is convenient and not necessarily random. In other words, a researcher gathers data from a sample that is lacking in diversity because it was easiest. College campuses like the one in show Community can have this problem in that most students are between 18-22 years of age and depending on the campus are leaned toward one ethnic group, California State University--Los Angeles, for example, is heavily Latino where as USC or UCLA would have a higher number of European ethnicities. The problem arises in that the sample group is not representative of the population and can only speak for the group you are testing. In the show Community's episode, Social Psychology, it is even worse because the sample is a small group of the lab assistants friends, which, though racially diverse, represent only the people that hang out with the lab assistants. Also the character running the research study gets upset because the newest lab assistant brought a friend that did not fit his paradigm, which means he was also condoning selective sampling within the most convenient group which would cause an unbelievable about of sample bias.
