The mean of a data set is equivalent to
AThe first quartile of that data
BThe second quartile of that data ✓ Correct
CThe third quartile of that data
DThe interquartile range of that data
Correct answer: (B) The second quartile of that data — The National Testing Agency dropped this item from evaluation, so no option is a settled key.
Explanation
★The National Testing Agency dropped this item from evaluation, so no option is a settled key.
★The mean is the arithmetic average of all the values in the data set.
★The quartiles and the interquartile range describe positions and spread, not the average.
★The second quartile equals the median, which is a middle value, not the mean.
★So the mean is not, in general, equal to any of the four options listed.
★Because the question has no truly correct option, it is defective as printed.
★For that reason the agency cancelled the question.
