Question

Conception about independent and identically distribued

in the real life explanation, for example assume the human height is i.i.d, then random variable E[X_bar1]=E[X_bar2]=...E[X_barn] and

X_bar=Sn/n, Sn=X1+X2...+Xn

so we draw one person, assume his height is 5ft7 then we draw 2 people, their average height will be 5ft 7, we draw 10 people and their average height is 5ft7?? is this correct???

Please correct my conception if I am not making sense and follow the comment as well
