Our largest number is 13. So we know the range. Now let's plot the median. And this will help us. One's getting this center line of our box, but then also we need to do that to figure out what these other lines are that kind of define the box, to define the middle two fourths of our number, of our data, or the middle two quartiles, roughly the middle two quartiles. It depends how some of the numbers work out. But this middle number, this middle line is going to be the median of our entire data set.
