Question

The _____ represents the second quartile in the box and whiskers plot?

• A. lower quartile
• B. upper quartile
• C. whiskers
• D. median

Answer 1

The correct option is D median

The median represents the midpoint of a data which divides the box into two halves which is also called the second quartile.

Example:
$2,6,\text{9},11,15$
Here, we have 5 numbers (odd), so the middle number 9 is the median of the given numbers. And represented in the second quartile of box and whisker plot.
$\therefore$ median = 9
