When you calculate a mean, the sign of the quotient always depends on the sign of the dividend. Why?

jimthompson5910 (jim_thompson5910):

here are the steps to finding the mean

jimthompson5910 (jim_thompson5910):

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

jimthompson5910 (jim_thompson5910):

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

jimthompson5910 (jim_thompson5910):

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
