Quizplus · Accepted Answer

Random sampling error is a common type of error that is due to chance variation in the elements selected for a sample. This type of error cannot be eliminated completely, but it can be reduced. Systematic error is a consistent bias in measurement or sampling, and it cannot be corrected by increasing the sample size. Self-selection error occurs when participants selectively decide to participate in a study, and it can result in biased samples. Non-sampling error refers to errors that are not related to the sampling process, such as errors in data entry or analysis.
