Question

Quizplus · Accepted Answer

Systematic errors are also called nonsampling errors because they are not related to the sampling process but rather other sources of error such as measurement biases or faulty equipment. Random sampling errors are those that occur due to chance and can be reduced by increasing the sample size. Interviewer errors are related to how the interviewer interacts with the respondent and can be reduced through training and monitoring. Nonresponse errors are related to those who do not respond to the survey and can be reduced through efforts to increase response rates.
