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 extending from the minimum to the lower quartile. The leftmost whisker's end (the leftmost vertical line) represents the minimum value.

Step2: Analyze the Given Box Plot

Looking at the box plot, the left whisker starts at the vertical line above the value on the axis. From the axis, the leftmost vertical line (whisker end) aligns with 30? Wait, no, wait the axis: 0,20,40,60,80,100. Wait, the left whisker's end (the left vertical line) is at 30? Wait no, let's check the axis. Wait the axis has marks: 0, 20, 40, 60, 80, 100. The left whisker (the horizontal line with the left vertical bar) is at 30? Wait no, maybe I misread. Wait the left vertical bar (the minimum) is at 30? Wait no, let's see the plot. Wait the left whisker: the left end is at 30? Wait no, the axis: 0, then 20, then 40. Wait the left vertical bar (minimum) is at 30? Wait maybe the axis has ticks between 20 and 40. Wait the left whisker's end (the leftmost vertical line) is at 30? Wait no, maybe the minimum is 30? Wait no, let's re-express. In a box plot, the minimum is the leftmost data point, represented by the left end of the left whisker (the left vertical line). Looking at the plot, the left vertical line (minimum) is at 30? Wait no, the axis: 0, 20, 40, 60, 80, 100. The left whisker (the horizontal line with the left vertical bar) is at 30? Wait maybe the minimum is 30? Wait no, maybe I made a mistake. Wait the left vertical bar (minimum) is at 30? Wait the plot: the left whisker (the horizontal line) has a left vertical bar at 30? Wait the axis: 0, 20, 40, 60, 80, 100. So between 20 and 40, the left vertical bar (minimum) is at 30? Wait no, maybe the minimum is 30? Wait no, let's check again. Wait the left whisker: the left end (minimum) is the left vertical line. So the x - axis: the left vertical line is at 30? Wait maybe the minimum is 30? Wait no, maybe the axis has ticks at 0, 20, 40, 60, 80, 100, and the left vertical bar (minimum) is at 30? Wait perhaps the minimum value is 30? Wait no, maybe I misread. Wait the left whisker's end (the left vertical line) is at 30? Wait the plot: the left horizontal line (whisker) has a left vertical bar at 30? So the minimum value is 30? Wait no, maybe the minimum is 30? Wait, let's confirm: in a box plot, the minimum is the leftmost point, the left end of the left whisker (the left vertical line). So looking at the plot, the left vertical line (minimum) is at 30? Wait the axis: 0, 20, 40, 60, 80, 100. So between 20 and 40, the left vertical bar is at 30. So the minimum value is 30? Wait no, maybe the minimum is 30? Wait I think the minimum is 30. Wait no, maybe I made a mistake. Wait the left whisker: the left end is at 30. So the minimum value is 30.

Answer:

30
