Question

the box-and-whisker plot below represents some data set. what is the minimum value of the data? answer attempt 1 out of 2

Explanation:

Step1: Recall box - and - whisker plot

In a box - and - whisker plot, the leftmost whisker (the small line at the left end of the plot) represents the minimum value of the data set.

Step2: Identify the minimum value

Looking at the number line below the box - and - whisker plot, the leftmost whisker is aligned with the value 30? Wait, no, wait. Wait, looking at the plot, the left whisker starts at 30? Wait, no, the number line has marks. Wait, the left end of the left whisker is at 30? Wait, no, let's check the number line. The number line has 0, 20, 40, 60, 80, 100. The left whisker (the horizontal line on the left of the box) has its left end at 30? Wait, no, maybe I misread. Wait, the left whisker's left end is at 30? Wait, no, looking at the plot, the left whisker starts at 30? Wait, no, let's see the plot again. Wait, the left whisker (the small vertical line on the left of the horizontal line) is at 30? Wait, no, the horizontal line on the left of the box goes from 30 to 40? Wait, no, the number line: each small tick? Wait, the number line has 0, then 20, 40, 60, 80, 100. The left whisker (the leftmost vertical line) is at 30? Wait, no, maybe the minimum is 30? Wait, no, wait, the left whisker's left end is the minimum. Looking at the plot, the left whisker starts at 30? Wait, no, let's count the ticks. From 0 to 20, there are some ticks, then 20 to 40. The left whisker (the left - most vertical line) is at 30? Wait, no, maybe I made a mistake. Wait, the box - and - whisker plot: the minimum is the leftmost point of the left whisker. Looking at the plot, the left whisker's left end is at 30? Wait, no, the horizontal line on the left of the box is from 30 to 40? Wait, no, the number line: 0, 20, 40, 60, 80, 100. The left whisker (the left - most vertical line) is at 30? Wait, maybe the minimum is 30? Wait, no, wait, maybe the left whisker starts at 30. Wait, let's check again. The left whisker (the small line on the left) is at 30. So the minimum value is 30. Wait, no, wait, maybe I misread. Wait, the left whisker's left end is at 30. So the minimum value of the data is 30? Wait, no, wait, the number line: 0, 20, 40, 60, 80, 100. The left whisker (the left - most vertical line) is at 30. So the minimum is 30.

Wait, maybe I made a mistake. Let's think again. In a box - and - whisker plot, the minimum is the value at the left end of the left whisker. So looking at the plot, the left whisker (the horizontal line on the left of the box) has its left end at 30. So the minimum value is 30.

Answer:

30
