Question

the box plot below represents some data set. what percentage of the data values are between 22 and 28?

Explanation:

Step1: Recall box - plot properties

In a box - plot, the box represents the inter - quartile range (IQR), which contains 50% of the data. The lower quartile ($Q_1$) is at the left - hand side of the box and the upper quartile ($Q_3$) is at the right - hand side of the box. The median is the line inside the box.

Step2: Identify quartile positions

Assume that 22 is $Q_1$ and 28 is $Q_3$. Since the data between $Q_1$ and $Q_3$ is the inter - quartile range.

Answer:

50%
