Question

the box plot below represents some data set. what is the minimum value of the data?

Explanation:

Step1: Recall box - plot components

A box - plot has a whisker on the left (minimum value side).

Step2: Locate the left - most point

The left - most point (the end of the left - hand whisker) gives the minimum value. Looking at the number line, each tick mark represents \(5\) units (since from \(0\) to \(20\) there are \(4\) intervals: \(\frac{20 - 0}{4}=5\)). The left - most point is at \(30\).

Answer:

\(30\)
