Find the range and the mid-range of the following sets of numbers. So what the range tells us is essentially how spread apart these numbers are. And the way that you calculate it is you just take the difference between the largest of these numbers and the smallest of these numbers. And so if we look at the largest of these numbers, I'll circle it in magenta, it looks like it is 94. 94 is larger than every other number here. So that's the largest of the numbers. And from that we want to subtract the smallest of the numbers.
