CompTIA Data+ (DA0-001) — Question 220

An analyst wants to determine whether a data set has errors and outliers in the variables. Which of the following types of analysis should the analyst perform?

Answer options

• A. Predictive
• B. Regression
• C. Prescriptive
• D. Exploratory

Correct answer: D

Explanation

Exploratory analysis is designed to help analysts discover patterns, spot anomalies, and check for data quality issues like errors and outliers. Predictive analysis focuses on forecasting future outcomes, regression analyzes relationships between variables, and prescriptive analysis suggests actions based on data insights, making them less suitable for identifying data set errors.
