A researcher receives completed questionnaires with missing responses for several important variables. What should be done first during data preparation?
Correct answer: B. Review the records and document missing data
- A. Replace every missing value with zero
- B. Review the records and document missing data
- C. Delete all questionnaires from the study
- D. Enter the missing values as positive results
Explanation
The researcher should review the records, determine the extent and pattern of missing data, and document the handling plan before analysis. Automatically entering zero can create false results because a missing response does not mean zero.
