Question

Quizplus · Accepted Answer

Sampling error is a measure of the difference between the sample statistic and the population parameter, which can only be calculated in probability sampling where each member of the population has a known chance of being included. Nonprobability sampling does not allow for this calculation because the selection of participants is not random, making it impossible to estimate the sampling error accurately.
