median is -ve means, all numbers to the left hand side are lesser than the median. What this means is they will have a negative sign and high numeric value compared to the median. All the numbers on to the right hand side are greater than the median. This means they will have a -ve sign and will have less numeric value than the median or just simply have a positive value. Now for the range, subtracting a -ve number from a +ve number will give a positive number, which is greater than the positive number itself. Similarly subtracting a large -ve number from a small -ve number will also give a +ve number, which is greater than any -ve number

Ex 1: { -8, -7 , -5 , 1, 2 } range is 2 - (-8) = 10

Ex 2: { -8, -7 , -5 , -1, -2 } range is -2- (-8) = 6
