Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

A retailer has transaction amounts for both convenience-store purchases and enterprise wholesale orders. Why might a single global outlier threshold be risky?

Choose the Best Answer

It may hide group-size differences but still preserves each group's natural amount scale. It prevents approximate quantile calculation from using numeric transaction amounts. It makes threshold management simpler, which is the main risk in model training. It can remove valid wholesale orders because the groups have different amount ranges.
