Question

use the box - and - whisker plot to answer the following.
(a) what is the tallest height?
(b) what is the median height?
(c) what is the first quartile ($q_1$) of the heights?

Explanation:

Step1: Recall box - and - whisker plot properties

In a box - and - whisker plot, the right - most end of the whisker represents the maximum value (tallest height), the line inside the box represents the median, and the left - hand side of the box represents the first quartile (\(Q_1\)).

Step2: Identify the tallest height

Looking at the right - most end of the whisker on the number line, it is at \(45\) cm.

Step3: Identify the median height

The line inside the box is at \(35\) cm.

Step4: Identify the first quartile (\(Q_1\))

The left - hand side of the box is at \(25\) cm.

Answer:

(a) \(45\)
(b) \(35\)
(c) \(25\)
