General Mental Ability, Quantitative Aptitude and StatisticsElementary statistics
- AMedian
- BSecond quartile
- C5th Decile
- DAll the above three
Explanation
The median is the middle value of an ordered series, dividing it into two equal halves. The second quartile and the 5th decile are defined identically — each marks the 50th percentile of the distribution. Since all three names denote the same positional value, the correct choice is (D), 'all the above three'.
