can someone please explain to me what happens to the mean and standard deviation of the distribution of sample means as the size of the sample decreases?

  • math -

    No real effect on mean.

    Standard Error of the mean (SEm) is the standard deviation for a distribution of means (vs. raw scores).

    SEm = SD/√n

    Insert some n values with the same SD to find out what happens to SEm.
