Question

Test scores of few students are plotted in the given line plot. Which of the following is a true statement regarding the given box plot?

• A. The distribution is skewed
• B. IQR is the best variability
• C. Median is the best center.
• D. The distribution is symmetrical

Answer 1

The correct option is D The distribution is symmetrical

Obsrving the given line plot, the left and right sides have equal number of values and the sides are mirror images of one another.


Hence, the distribution is symmetrical.
Hence, the option "The distribution is symmetrical" is true.


Since, the shape of distribution is symmetrical, mean is the best center of measure.

Hence, the option "Median is the best center" is not true.


Since, the distribution is not skewed, MAD is the best variability, hence, "IQR is the best variability" is false.

Since, the distribution is symmetrical "The distribution is skewed" is not true.
