CompTIA Data+ (DA0-001) — Question 2

Which of the following BEST describes the issue in which character values are mixed with integer values in a data set column?

Answer options

• A. Duplicate data
• B. Missing data
• C. Data outliers
• D. Invalid data type

Correct answer: D

Explanation

The correct answer is D, as mixing character values with integers creates an invalid data type for that column, which can lead to processing errors. Options A and B do not relate to the issue of data type conflicts, while C refers to unexpected values that lie outside the normal range, not specifically to type mismatches.
