Question

the box plot below represents some data set. approximately what percentage of the data values are less than 60?

Explanation:

Step1: Recall the properties of a box - plot

In a box - plot, the median divides the data set into two halves. The lower half of the data is below the median and the upper half is above the median. Also, the box - plot is divided into quartiles. The first quartile ($Q_1$) represents the 25th percentile, the median ($Q_2$) represents the 50th percentile, and the third quartile ($Q_3$) represents the 75th percentile.

Step2: Locate the position of 60 on the box - plot

Looking at the box - plot, 60 is the median (the line inside the box).

Answer:

50%
