Study Notes
Introduction
- Non-sampling errors in household surveys can be variable or fixed. Variable errors are similar to sampling errors and change across samples. Fixed errors, or bias, are consistent across samples.
- Non-coverage occurs when individuals or groups in the population have no chance of being selected for the sample.
- Non-response occurs when data cannot be collected from individuals selected for the sample. This can be due to refusal, language barriers, health limitations, or absence during the survey period.
- Measurement errors originate from various sources like respondents, interviewers, supervisors, and data processing systems. Respondents may forget information or provide inaccurate answers, especially about sensitive topics.
- Survey designers consider four dimensions in relation to errors: defining the error, measuring the error size, developing procedures to reduce the error, and compensating for the error in final results.
Non-Observation and Measurement Errors
- Chapters VIII and IX analyze non-observation and measurement errors conceptually, illustrating different types of errors.
- Chapters X and XI provide a deeper examination of these errors, exploring the impact on survey quality and presenting a case study from Brazil.
