Quincy · Answer 1

A Quartile is a 1/4 of the values which are arranged in numerical order. Quartile 2 (Q2), which is also called the Median of the data set. It means half of the data set on each side of the Quartile 2.

Hence theb est answer is:

a. the data value 2.5 will lie Below the second quartile.

Because 2.5 is lower value than the 4.2 and it must lie on the left of 4.2.

Josephine Bentley · Answer 2

The second quartile is also the median. which is 50% of the data. So 1/2 of the data lies below it, and 1/2 of the data lies above it.

the correct answer would be A. the data value of 2.5 will lie below the second quartile.
