Hi, I'm Rachel, and today we're going to be going over how to construct a box plot. A box plot, or as a lot of people refer to it, is a box and whiskers plot, is something that we use when have a bunch of data and we wanna organize in a nice way, usually based on the median, which is the middle number. So, let's say we have the numbers one through seven. So, I'll write them out, one, two, three, four, five, six and seven. We space them out, evenly, on the number line, and this, these are the numbers in our range of data. Well, what's the smallest number? It is one. And, what's the largest number? It is seven. So, we do dots on the number line, on the smallest and biggest number. Then, we find the median, or the middle number. We can literally start off at the edges, and go in 'til we find the middle number, which is the four, and we put a dot there, at the median, the middle number. And, this is what our box looks like. So, we draw a box, like this, and then, we usually find the median of this range, and this range, from the median to the smallest number, and the median to the biggest number. Now, the median, here, as you can see, it doesn't land perfectly. It's right in between the two and the three. It's gonna be at two point five. We do another box, another dot. And, then, here, it's gonna be right in between the five and the six, at five point five, and that is our other line. And sometimes, you know, you can do lines like this, it depends on what it looks like. But, as you can see, you have a box and you have whiskers, as well. I'm Rachel, and thank you for learning with me today.
