 So see if I understand this. It does not matter how many numbers you have to add together you would divide it from that amount of numbers and then take the two middle numbers and divide that by two? Foe example if I had 100, 150, 300, 450, 500, 550, 600, 650, 800, 900 Now I add all of these together such as 100 + 150 +300 + 450 + 500 + 550 + 600 + 650 + 800 + 900/ 10 = 833.33. Then I take 500 + 550/2 = 525? Do I have this correct? I am trying to understand this all.
