no - in real life, each person has a child at some age. An aggregate of those numbers is still showing individual lives. Similar reasoning for "2.5 children" .. that is "average" but exactly zero people out of millions have 2.5 children in reality.
no sorry, its a beginner mistake to think that there are average people at all. For example, people who are not adults.. there is no meaning to "average" for children at 2 years, 6 years, 8 years, 12 years.. they are different. Its not an average.. it is a collection of groups.. Human populations are collections of groups that overlap in characteristics.. there is no "average" person
from the other side, a real number product of mean, average etc. is .. a number. You can do lots of math with numbers, and you will get consistent results in a number sense.. but the model is not the creation
