Robin Dunbar, a leading anthropologist at Oxford University who studies social networks, has suggested that there is a magical for social networks that humans can manage: any grouping larger than $150$ people becomes overwhelming.

With that in mind, a group of researchers at Facebook wanted to study more about how their average user manages their social networks. One study of $225$ Facebook users found a mean of $338$ friends. Facebook knows from prior studies of their users that the standard deviation is $44.$
