(a) What is the difference between the standard deviation of a set of scores and the standard error of the mean?
(b) Do behavioral science researchers want the standard error of the mean to be small or large? Why?
(c) What happens to the standard error of the mean as the sample size (N) becomes smaller? Why? What does this imply about the dangers of using samples in behavioral science research that are very small?
(d) What happens to the standard error of the mean as the SD of the original scores in the population becomes larger? Why?
