Outlier Finder — illustrative example

INPUT
Values with row IDs: A=10, B=11, C=12, D=100. Use a supplied review rule: flag values above twice the median. Do not delete records.

RESULT
Sorted values: 10, 11, 12, 100.
Median: (11 + 12) / 2 = 11.5.
Threshold: 2 × 11.5 = 23.
Flagged: row D, value 100, because 100 > 23.
A, B and C do not exceed the threshold. This is the requested review heuristic, not evidence that D is an error.

REVIEW
Outliers depend on the chosen rule and context. A flagged value may be valid, so show the calculation and keep the original record.

This is a teaching example, not a live execution record.
