The mean of this and this is going to be, is going to be 15. And we know that the mean of, we know that the mean of this and this is going to be 10 and that Mean of this and this, is going to be 13. These middle two values, we have an even number now so, the median is going to be We know, we know that the, we know that the mean of And so here we know that the minimum, we know that the minimum is seven, we know that the maximum is 16. So let's see, one, two, three, four, five, six, seven, eight. Well we could do something like, let's say that we have eight. And we could try it out with other, other scenarios where. And so 75% are 10 or older, well, this value, in this case, six out of seven are 10 years old or older. Similarly, this couldīe 13, it could be 14, it could be 15, and so any of those values wouldn't change it. It wouldn't change thisīox and whiskers plot. It wouldn't change what these medians are. It could be 10, it could be 11, it could be 12, it could be 13. So we know that's sevenĪnd then that is 16. Us what the minimum, the minimum is seven. I'm just trying to see what I can learn about different types of data sets that could be described by Middle, just like that, and maybe I have three on either side. I have an odd number, I would have 13 in the We could do a scenario where well let's see, let's see if I can, I can construct something So we could do a scenario, let's see if we can do. So they don't know, we don't know, based on the information here exactly how many students are at the party. But to make that a little more tangible, let's look at some, so I'm feeling, I'm feeling good that this is true, but let's look a few more examples to make this a little more concrete. In fact, you could even have a couple of values in the first Saying 10 years old or older that this is going to be, this is going to be true. To be in the third quartile, and approximately 25% are going to be in the fourth quartile. Numbers are in the second, or roughly, sometimes it's not exactly, so approximately, I'll say roughly 25% are going to be in this second quartile, approximately 25% are going And actually, let me do this, let me do this in a different color. This, this feels right, because 10 is, 10 is the value that is at the beginning At least 75% of the studentsĪre 10 years old or older. So it is the case thatĪll of the students are less than 17 years old. Here, that the maximum age, that's the right end of That all of the students are less than 17 years old. Have enough information, it could go either way. The box and whiskers plot, which of these are for sure true, which of these are for sure false, and which of these we don't Pause the video, look at these statements, and think about which of these, based on the information in And what I have here areįive different statements and I want you to lookĪt these statements. And what I'm hoping to do in this video is get a little bit of A box and whiskers plot showing us the ages of
