Document Summary
Standard error: standard deviation of the sampling distribution. Measure of how much random variation we would expect from samples of equal size drawn from the same population. Sampling distribution: a theoretical distribution of any statistic that one would get by repeatedly drawing random samples of a given size from the population and calculating the statistic of interest for each sample. Sampling distribution of the mean: the distribution of scores that would be generated if one were to repeatedly draw random samples of a given size from a population and calculate the mean for each sample drawn. Expected value of the mean: the value of the mean one would expect to get from a random sample selected from a population with a known mean. = x= xbar (or replace sigma with s for sample)
