Collecting High-Quality Data – Quiz 3

Quiz Question Explanations

Question 1

Error can creep in from all of the above. Questionnaire design – questions can be phrased ambiguously, with multiple interpretations; respondents can misunderstand questions and misreport accidentally, or can choose to misreport; enumerators can hear responses incorrectly, or choose to enter something differently to make their life easier; and as we saw in the famous cell reference error in the Reinhart and Rogoff paper, it can come from the analysts.

Question 2

Before data collection, we should pilot and train enumerators.

Question 3

During data collection, we should conduct backchecks, audio audits, and high frequency checks, and retrain enumerators if necessary.

Question 4

If we find errors after data collection, we should conduct a sensitivity analysis-determine how much our results change if we remove the problematic indicator, or if we place reasonable bounds for errors.
