Question

the box plot below represents some data set. what is the minimum value of the data? (box plot and number line with 0, 50, 100, 150, 200)

Explanation:

Step1: Recall box plot components

A box plot has a whisker extending to the minimum value. The left - most whisker's end represents the minimum.

Step2: Identify the minimum from the plot

Looking at the box plot, the left whisker ends at 25 (by counting the intervals: from 0 to 50, the first mark after 0 is at 25? Wait, no, let's re - examine. Wait, the x - axis has marks at 0, 50, 100, 150, 200. The left whisker starts at 25? Wait, no, maybe the scale: each small tick? Wait, the left whisker's end is at 25? Wait, no, looking at the plot, the left whisker (the horizontal line with the vertical tick) is at 25? Wait, no, maybe I misread. Wait, the x - axis: 0, then some ticks, then 50. Wait, the left whisker's minimum value is at 25? Wait, no, let's check again. Wait, the box plot's left whisker (the line before the box) has its end at 25? Wait, no, maybe the correct minimum is 25? Wait, no, looking at the x - axis, the leftmost whisker's end is at 25? Wait, no, perhaps the scale is such that between 0 and 50, there are 4 small ticks, so each tick is 10? Wait, 0, 10, 20, 30, 40, 50. Wait, no, the left whisker's end is at 25? Wait, no, the correct way: in a box plot, the minimum is the value at the end of the left whisker. From the plot, the left whisker (the horizontal line with the vertical bar) is at 25? Wait, no, maybe I made a mistake. Wait, the x - axis: 0, then 50, 100, 150, 200. The left whisker starts at 25? Wait, no, the left whisker's end is at 25. Wait, but maybe the correct minimum is 25? Wait, no, let's look again. The left whisker (the line before the box) has its end at 25. So the minimum value is 25? Wait, no, maybe the scale is different. Wait, the x - axis: 0, then 50, so between 0 and 50, there are 4 intervals, so each interval is 10. So 0, 10, 20, 30, 40, 50. The left whisker's end is at 25? No, maybe the vertical tick is at 25. So the minimum value is 25. Wait, no, perhaps I misread. Wait, the correct minimum is 25? Wait, no, let's check the box plot again. The left whisker (the horizontal line with the vertical bar) is at 25. So the minimum value of the data is 25.

Wait, maybe I made a mistake. Let's re - evaluate. The box plot: the leftmost point (the end of the left whisker) is at 25. So the minimum value is 25.

Answer:

25
