Well, I know that if I have a mileage more than 200,000, I'm going to be in the fourth quartile, but I don't know how many values I have sitting there in the fourth quartile, just looking at this data over here. So that's not going to be useful for answering that question. Let's look at the second question. Which display can be used to find the median distance was approximately 140,000 kilometers? Well, to calculate the median, you essentially want to be able to list all of the numbers and then find the middle number. And over here, I can't list all of the numbers. I know that there's three values that are between zero and 50,000 kilometers, but I don't know what they are.
