CompTIA Data+ (DA0-001) — Question 44

An analyst is working with the income data of suburban families in the United States. The data set has a lot of outliers, and the analyst needs to provide a measure that represents the typical income. Which of the following would BEST fulfill the analyst’s goal?

Answer options

• A. Median
• B. Mean
• C. Mode
• D. Standard deviation

Correct answer: A

Explanation

The median is the best measure of central tendency in this case because it is not affected by outliers, thus providing a more accurate representation of typical income. The mean, while common, can be skewed by extreme values, making it less reliable here. The mode represents the most frequently occurring income but does not reflect the overall distribution effectively. Standard deviation measures variability and does not indicate typical income.
