Databricks Certified Machine Learning Professional — Question 58

Which of the following is a simple statistic to monitor for categorical feature drift?

Answer options

• A. Mode
• B. None of these
• C. Mode, number of unique values, and percentage of missing values
• D. Percentage of missing values
• E. Number of unique values

Correct answer: C

Explanation

The correct answer is C because it encompasses multiple statistics that provide a comprehensive view of categorical feature drift. The mode alone (A), percentage of missing values (D), or number of unique values (E) do not provide as complete a picture as the combination in C, which includes all relevant aspects of categorical data monitoring.
