Detailed explanation-1: -If the sample is not representative of the larger population, then the survey results are potentially biased. Failure to initially specify the population, problems in selecting a sample, and poor response rate can all lead to sampling error and bias.
Detailed explanation-2: -Systematic non-sampling errors are worse than random non-sampling errors because systematic errors may result in the study, survey or census having to be scrapped. The higher the number of errors, the less reliable the information. When non-sampling errors occur, the rate of bias in a study or survey goes up.
Detailed explanation-3: -population. ➢ Nonprobability (Non-Representative) ❖ A sample that is not selected in such a way as to be representative of the. population.
Detailed explanation-4: -The “total survey error” paradigm (Groves et al. 2009) identifies multiple sources of error in surveys: measurement error, processing error, coverage error, sampling error, nonresponse error, and adjustment error. Administrative data may also have some of these errors.
