How do unit increases in sample size (i.e., going from 1 to 2 to 3 and so on) impact the mean and variance of the sampling distribution of totals? As n increases, the mean remains unchanged, but the variance increases on a linear basis The mean increases by

E(x)

and the variance by

Var(x)

with each unit increase in

n

The total of the averages and the total of the variability increase logarithmically with unit increases in

n

The mean remains unchanged

(u)

, but the variance decreases with unit increases in

n

The mean and the variance remain unchanged
