Walk me through your process for ensuring accuracy and attention to detail in a project or report.

Situation

For my undergraduate thesis, my team collected survey data from 200 respondents across four departments. The analysis would be used to recommend curriculum changes, so accuracy was critical.

Task

As the data analyst, I had to design the collection method, input the data, and produce error-free descriptive statistics for our final paper within two months.

Action

I built the questionnaire in Google Forms with built-in validation rules to eliminate out-of-range answers. Before mass distribution, I piloted it with 10 students and revised three ambiguous items. For data entry of paper responses, I used a double-entry system where my teammate and I encoded separately, then matched for discrepancies. I ran spot checks on 10% of the records by physically comparing them to the hard copies. When analytics showed a nonsensical correlation, I traced it to a reversal in one survey item and corrected the entire variable.

Result

Our final dataset had zero entry errors confirmed, and the thesis panel rated our methodology and analysis as exceptional, giving us a grade of 98%. Our findings were later used by the department for program improvement.
