The second quartile of a data set is 4.2. Which statement about the data values is true?
a. the data value 2.5 will lie delow the second quartile
b.The data value 4.7 will lie below the 2nd quartile
c. one fourth of the data values are less than or equal to 4.2 and 3/4 are above 4.2
d.1/4 of the values are less than or equal to 4.2 and 1/2 of the values are above 4.2
e. 1/4 of the values are above 4.2 and 1/2 of the values are less than or equal to 4.2

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.

The statement about the data values is true; A the data value 2.5 will lie below the second quartile.

What are quartiles?

When we get data that can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each group approximately possessing 25% of the data.

The second quartile of a data set is 4.2.

The second quartile (also called median) is approximately in mid of the data.

The first quartile is located such that 25 % of the data lie below the first quartile and 75 % of the data lie above the first quartile.

Therefore, The first quartile of a data set is 2.5. this statement represents that 1/4 of the values are less than or equal to 2.5, and 3/4 of the values are above 2.5.
