Question 500
A Power BI team has selected this approach: Review time granularity and seasonality assumptions before interpreting anomaly points. The original business context is: A report's anomaly detector flags every Sunday low as abnormal even though it is a weekly business pattern. Which observation best indicates the requirement was met?
Explanation
Correct Answer
Routine Sunday troughs are treated consistently while true exceptional drops remain flagged. It provides the required observation for the chosen implementation: Review time granularity and seasonality assumptions before interpreting anomaly points. This test addresses the stated business constraint directly.
Incorrect Answers
The outliers remain visible and the summary differentiates typical from extreme refunds. That check would be meaningful for the separate case: A retail report has a few exceptionally large refunds that distort the average. It would not directly verify this scenario's selected implementation: Review time granularity and seasonality assumptions before interpreting anomaly points.
Branch totals reconcile with the cancellation measure as users drill down. That check would be meaningful for the separate case: A customer retention report needs a decomposition tree to break cancellations by channel, product and region. It would not directly verify this scenario's selected implementation: Review time granularity and seasonality assumptions before interpreting anomaly points.
The explanation highlights verifiable categories associated with the observed change. That check would be meaningful for the separate case: An analyst wants Power BI to explain a sudden rise in returns by examining category and region dimensions. It would not directly verify this scenario's selected implementation: Review time granularity and seasonality assumptions before interpreting anomaly points.
