In this case, the population mean (?) is often equal to the sampling distribution mean, and the standard error of such sampling distribution (?x) can be determined using the population standard deviation (?), the sample size and the population size. Using mathematical equation, the equations below serve to indicate the mathematical relation between the population mean and the sampling distribution, and the relation between the sample distribution, the population standard deviation, the populationa dn the sample size as shown ?
