Well, each section is 1/4 of the data. The first point, the beginning of the plot, is the minimum. The last point is the maximum. The line in the middle of the box is the median, and one end of the box is the quartile 1 median. The other end of the box is the quartile 2 median. The box itself represents the middle of the data, or the interquartile range. Again, it’s good to remember each section is 1/4 of the data, but not all the data is spread out the same way. Some data is close together, meaning the box is smaller, like 10, 11, and 12. Some is far apart, meaning the box is longer, like 3, 8, and 15. We covered this yesterday in pre-algebra! Hope this helps!
