What is the Range? | Example Question | Math with Mr. J

[Music] Welcome to Math with Mr. J. In this video, we're going to answer the question, the distances in miles a delivery driver traveled over the past 7 days are shown below. What is the range of the distances? Now, remember the range tells us how spread out our data is between the highest value and lowest value. So basically how far apart those values are. In other words, range tells us about the span of our data. We find the range by taking the highest value and subtracting the lowest value. So we're finding the difference between the highest and lowest values. The first thing that we're going to do here is put the data in order from least to greatest. So, we're going to organize this, and that's going to help us clearly see what our lowest and highest distances are. It looks like our lowest distance is 110 miles. So, 110 miles. Cross that off. Next, it looks like 112. Then, we have 125. Next is 128, then 133, then 140, and our greatest distance 142 miles. And now our data is in order from least to greatest. Now again, range equals the highest value minus the lowest value. So our range here is going to be our greatest 142 miles minus our lowest 110 miles. 142 minus 110 gives us a range of 32 miles. So our correct answer here is choice D. Again, 32. So there you have it. There's the range of those distances. Just remember, we find the range by taking the highest value and subtracting the lowest value. So whether you are studying for a test, learning this in class, just looking for a problem to solve, or whatever the case may be, I hope that helped. Thanks so much for watching. Until next time, peace.
