When there is a likely chance that any member of the population will be selected for the sample, the sample is said to be random. This ensures that the sample is representative of the population and minimizes bias. A controlled sample implies that some element of the sample selection process is predetermined or restricted, potentially introducing bias. A biased sample is one that is not representative of the population due to some factor that skews the selection process. A non-random sample is one that does not involve a random selection process, potentially introducing bias.
