Unformatted text preview: This fluctuation is the standard error If your sample is the entire population (sample = population) then your standard error = 0 Maximum standard error: if your sample number is 1, then standard error is equal to that of standard deviation so…. x = σ Sampling distribution stuff-collection of sample means for all possible random samples of a particular size (n) that are drawn, with replacement, from the population- this is NOT a distribution of scores, but a distribution of statistics- sample means tend to center on population mean- distribution is approximately normal (helps us later)- we can ask/answer questions about sample means (ex: p (sample mean > 7)? ) Central Limit Theorem-“ for any population with mean μ and standard deviation σ , the distribution of sample means for sample size n will have a mean of μ and standard deviation of n , and will approach a normal distribution as n approaches infinity.”...
