A hospital research team has completed data collection for a study of catheter-associated urinary tract infection. What should it do before entering the results into statistical software?
Correct answer: A. Check the data for completeness and coding errors
- A. Check the data for completeness and coding errors
- B. Delete all unusual values from the data set
- C. Change missing responses to the expected answer
- D. Begin writing conclusions from the research question
Explanation
Data cleaning includes checking completeness, coding, ranges, and possible entry errors before analysis. Unusual values should be investigated rather than automatically deleted, and missing responses must not be replaced without a justified method.
