122 1 08888 01112. The Sampling Distribution of the Sample Mean If repeated random samples of a given size n are taken from a population of values for a quantitative variable where the population mean is μ mu and the population standard deviation is σ sigma then the mean of all sample means x-bars is population mean μ mu. Whatever the shape of the population distribution the distribution of sample means is.

Assume that the distribution of SAT scores of all examinees is normal with a mean of 1020 and standard deviation of 153. 1 Let X. If the population is infinite and sampling is random or if the population is finite but were sampling with replacement then the sample variance is equal to the population variance divided by the sample size so the variance of the sampling distribution is given by. It describes a range of possible outcomes that of a statistic such as the mean or.
