r u there @texaschic101

OpenStudy (anonymous):

OpenStudy (texaschic101):

first we find the mean..the average (9 + 12 + 18 + 20 + 26 + 35) / 6 = 120/6 = 20 now we take every number from the mean (even if its negative, make it positive) 20 - 9 = 11 20 - 12 = 8 20 - 18 = 2 20 - 20 = 0 20 - 26 = -6 = 6 20 - 35 = -15 = 15 now we take the mean of those numbers (11 + 8 + 2 + 0 + 6 + 15) / 6 = 42/6 = 7 so absolute deviation is 7

OpenStudy (anonymous):
