Central Limit Theorem applies to distribution of sample means for any population

Standard Deviation - average distance of scores from population mean

Standard Error - average distance of sample means from population mean

Z Score - # of SD's you are away from the mean

Confidence Level - plus or minus 2 standard errors will give us a 95.44% confidence interval

SS - sum of the squared deviations around the mean

SD (population) = SS/N = (x-u)^2

SD (sample s) =

SE (P) =
