Best ResponseYou've already chosen the best response.1For each dot, write down its number, add them up and divide by the number of dots. what do you get ?

Best ResponseYou've already chosen the best response.1the places with 2 dots means you have that number twice. the numbers are 50, 76, 78, 79,79, etc

Best ResponseYou've already chosen the best response.1everywhere you see one dot, use that number if you see two dots, use that number twice you will have a number for every dot (10 numbers)

Best ResponseYou've already chosen the best response.1it should add up to 770 and divide by 10 to get 77 that is the average (the mean) of the 10 numbers. Now add up all the numbers except for the 50 (50 is the "outlier" because it lies far away from the other numbers) I would do 77050 and then divide by 9 (the number of values we have after tossing the 50)

Best ResponseYou've already chosen the best response.1so the mean changed from 77 to 80 I got 720/9 = 80 for the second mean
