WebIt's important to identify potential sources of bias when planning a sample survey. When we say there's potential bias, we should also be able to argue if the results will probably be an overestimate or an underestimate. Try to identify the source of bias in each scenario, and speculate on the direction of the bias (overestimate or underestimate).
WebSampling frame (synonyms: "sample frame", "survey frame") is the actual set of units from which a sample has been drawn: in the case of a simple random sample, all units from the sampling frame have an equal chance to be drawn and to occur in the sample.
