Answer: Median.
- A Range
- B Variance
- C Median
- D Standard deviation
Correct answer: C. Median
Explanation: Measures of central tendency (location): mean, median, mode. Others listed measure spread (dispersion).
In a perfectly normal (bell-shaped) distribution, mean, median, and mode all coincide at the centre; about 68% of data falls within 1 standard deviation of the mean, 95% within 2, and 99.7% within 3 - the empirical rule used to judge how typical or extreme a value is.
