Question
Errors made by fieldworkers are classified as:Group of answer choicesSampling errorsNon-sampling errorsRecording errorsFieldworker errors
Solution
The errors made by fieldworkers can be classified as:
-
Sampling errors: These errors occur when the sample obtained does not accurately represent the population. It could be due to bias in selection, non-response, or undercoverage.
-
Non-sampling errors: These are errors that can occur at any stage of the data collection process, other than during sampling. They can be due to factors such as measurement error, data processing error, or response error.
-
Recording errors: These are errors that occur when the data is recorded incorrectly. This could be due to misunderstanding, misinterpretation, or even simple mistakes like typos or mishearing.
-
Fieldworker errors: These are errors specifically made by the fieldworkers. They could be due to lack of training, misunderstanding of instructions, or bias in data collection. This could also include errors in data entry if the fieldworker is responsible for this task.
