RangeSo, in the set { 2, 5, 8, 2, 1, 4, 3 } the highest number is 8 and the lowest number is 1, so the range is 8 - 1 = 7 <--range!If there are any negative numbers in the set, then you have to be really careful, because subtracting a negative number is the same thing as adding the positive number. So, in the set { 5 -1 6 -2 0 }The highest number is 6 and the lowest number is - 2, so the range is: 6 - (-2) = 6 + 2 = 8 (remember, a minus times a minus is a plus!)Think of it as the distance between 6 and - 2 on the number line, like this: ---|---|---|---|---|---|---|---|---|---|---|---|-- ... -3 -2 -1 0 1 2 3 4 5 6 7 8 |<------------ 8 -------------->| For a more in-depth discussion of range and other statistics, see the statistics notes. So, here is a problem for you: What is the range of this set of numbers? { 9 4 8 9 2 -1 3 4 }Range = _______ |
