CompTIA Data+ (DA0-001) — Question 327

A data analyst has removed the outliers from a data set due to large variances. Which of the following central tendencies would be the best measure to use?

Answer options

• A. Range
• B. Mean
• C. Mode
• D. Median

Correct answer: B

Explanation

The mean is the best measure of central tendency to use when outliers have been removed because it takes all data points into account, providing a comprehensive average. Other measures like the mode and median can be influenced less by extreme values, but in this case, the removal of outliers makes the mean more reliable. The range is not a measure of central tendency, so it is not applicable here.
