QuestionQ42

Data analysis

A data analyst produces a report on the time elapsed between sequential events. The dataset contains several rows with negative integers in the elapsed-time column. What is the best way to address this issue?

Explanation

Negative elapsed-time values indicate a potential data-quality or event-ordering problem. Validating the dataset before analysis identifies the source of the invalid values and supports an appropriate corrective action without discarding or altering data prematurely.
