SAMPLING ERRORS Appendix B The estimates from a sample survey are affected by two types of errors: (1) nonsampling errors, and (2) sampling errors. Nonsampling errors are the results of mistakes made in implementing data collection and data processing, such as failure to locate and interview the correct. Sampling Errors—These errors occur because of variation in the number or representativeness of the sample that responds. Sampling errors can be controlled by (1) careful sample designs, (2) large samples, and (3) multiple contacts to assure representative response. The errors mainly arising at the stages of data collection and processing of data are termed. non-sampling errors. Thus non-sampling errors are common to both censuses and sample surveys. 3.
