Document Summary

A sample statistic (sample mean) from repeated samples with the same sample size will have a distribution the distribution of a sample statistic is called sampling distribution of the mean. A distribution of raw scores of a variable in a sample is the frequency with which possible values occur in the sample. A sampling distribution is a distribution of a statistic of a variable (the frequency with which possible values of that statistic occur) in samples of a specific size. The sampling distribution of the mean is a distribution of means obtained by selecting samples of a specific size from a population. Distribution of means across a population of samples. Distribution of raw scores across a population of subjects. If many random samples of size n are drawn from a population, The mean of sampling distribution of the mean will have a mean equal to the population mean: m = .
