How Would You Handle Duplicate Records in a Dataset?
Data analysts frequently have to deal with data quality issues like duplicate records. This question tests your hands-on understanding of data cleaning and preprocessing.
To impress the interviewers, walk through your systematic process for identifying, confirming, and removing duplicate entries:
-
First, I would run checks for duplicate values in key fields like customer ID, name, email address, etc. This would flag potential duplicates.
-
Next, I would confirm which flagged records truly represent the same entity versus false positives. Comparing values across all fields would verify duplicates.
-
For confirmed duplicates, I would decide which record to keep and drop the others. The record with the most complete information would be retained.
-
Finally, I would delete the duplicate records, ensuring no data loss, then re-run analysis on the cleaned dataset.
