单选题

Which of the following statements is most accurate?

A、 The first quintile generally exceeds the median.
B、 The first quintile generally exceeds the first decile.
C、 The first quintile generally exceeds the first quartile.

【正确答案】 B

【答案解析】

The first quintile is the 20^th percentile. The first decile is the 10^th percentile, the first quartile is the 25^th percentile, and the median is the 50^th percentile. While it is possible that these various percentiles or some subsets of them might be equal (for example the 10^th percentile possibly could be equal to the 20^th percentile), in general the order from smallest to largest would be: first decile, first quintile, first quartile, median.
