When you calculate a mean, the sign of the quotient always depends on the sign of the dividend. Why?
here are the steps to finding the mean
step 1) add up all the numbers step 2) divide that sum you got in step 1 by the number of numbers in the list
when you get to step 2, you will ALWAYS be dividing by a positive number why? because this number is the count of numbers in the list. You can't have a negative count
so because mean = (sum of numbers)/(number of numbers) and the "sum of numbers" part is the dividend, this means that the mean will only be negative if the dividend is negative
