Which of the following measures is MOST appropriate for describing the central tendency of data on monthly income in a city where a few executives earn extremely high salaries?
- A Mean
- B Mode
- C Median ✓
- D Standard deviation
Correct answer: C. Median
Explanation
Median is the preferred measure of central tendency for skewed distributions because it is not affected by extreme outliers. High-earner salaries will skew the mean upward, making it unrepresentative. Mode represents the most frequent value and standard deviation is a measure of dispersion, not central tendency.
