If you need an illustration:
The average of (1,4,3) is 8/3 2.67. If you add on another 4, then you have the average of (1,4,3,4) is 3. (It changed substantially.)
The average of (1,4,3,4,1,2,3,4,2,3,4,1,2,3,2,3,1,4,4,4,2) is 19/7 2.71. Adding on another 4, the average of (1,4,3,4,1,2,3,4,2,3,4,1,2,3,2,3,1,4,4,4,2,4) is 61/22 2.77. (It did not change very much.)
