What is handling outliers conceptually?

< 1 min read

Handling outliers means identifying and managing data points that deviate significantly from normal values.
In my project, a few orders had negative sales due to system errors.
We flagged them for review or replaced them with corrected values.
Extreme values in revenue or quantity were sometimes capped or removed.
Outliers can distort averages, totals, and trends in dashboards.
Power Query or DAX logic was used to detect based on thresholds or standard deviation.
Business rules decided whether to keep, adjust, or exclude outliers.
Handling them ensures accurate KPIs and reliable reporting.
It also prevents misleading insights for decision makers.
So managing outliers maintains data integrity and analysis quality.
