standard error of the mean
the standard deviation of the sampling distribution
how do you calculate the standard error of the mean
determine the mean for each sample and then calculate the SD for the distribution of sample means ( SD of pop o sub X bar)
central limit theorem
a theorem which states that for any population with the mean and the standard deviation, the distribution of sample means for sample size N will have a mean of mew and a SD of ò/square root of N and will approach a normal distribution as N approaches infinity
standard error of the mean equation
o sub X bar= o/ square root of N
what do we need to know for the sampling distribution
the mean and the standard error of the mean
