CompTIA DataX (DY0-001) — Question 16

During EDA, a data scientist wants to look for patterns, such as linearity, in the data. Which of the following plots should the data scientist use?

Answer options

• A. Violin
• B. Box-and-whisker
• C. Scatter
• D. Q-Q

Correct answer: C

Explanation

The scatter plot is the correct choice because it visually represents the relationship between two variables, allowing the data scientist to easily identify linear patterns. In contrast, the violin and box-and-whisker plots are useful for showing data distribution, and the Q-Q plot is primarily used for assessing normality, making them less suitable for detecting linearity.
