The Mean & Standard Deviation of the Sampling Distribution of the Means (an option is to list the frequency of each mean: see part 3 of Practice question) To display this distribution, we list the value of each sample mean x-bar and ![]() The Sampling Distribution of the Sample MeansÄefinition: The probability distribution of the sample meansÄerived from all possible samples of a given size from a given population. ![]() We then use this new distribution, The Sampling Distribution of the Sample Means, to find the mean of and an estimate for the standard deviation of the parent population. ![]() When we need information about the parameters of a population (especially a finite population) we collect many samples of a given size n from the population, then set up the probability distribution for the means of all our samples.
