CompTIA DataX (DY0-001) — Question 34

A data analyst wants to find the latitude and longitude of a mailing address. Which of the following is the best method to use?

Answer options

• A. One-hot encoding
• B. Binning
• C. Geocoding
• D. Imputing

Correct answer: C

Explanation

The correct answer is C, Geocoding, as it specifically refers to the process of converting addresses into geographic coordinates. A, One-hot encoding, is used for categorical variable transformation and is not relevant here. B, Binning, involves grouping numerical data into bins and does not apply to address location, while D, Imputing, is concerned with filling in missing data rather than determining geographic coordinates.
