the range statistics the range is the difference between the lowest and highest values example in 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6
Differences Between Range and Midrange. Range is the difference between the largest value in the set of numbers and the smallest. To find the range you do not have to put the numbers in order, but you do have to identify the largest and the smallest.Then you simply subtract the lowest from the highest.This shows us how much variation there is in the set of numbers.The key difference is that for midrange we want to find the MIDDLE of the RANGE (hence midrange). We do this by finding the average of the lowest and highest values.hen you simply subtract the lowest from the highest. This shows us how much variation there is in the set of numbers.
