Quizplus · Accepted Answer

A sampling error results from using a sample instead of a population.
Key Takeaway: A sampling error occurs from using a sample to collect date instead of a population to estimate a population parameter. For example, if a company uses a sample of 50 employees (out of a total population of 600), then a sampling error would occur as the estimate can only approximate the population parameter. In general, a sampling error can be reduced by choosing a large, representative sample from which to collect data.
