Statistics question

Question

A sample of n = 36 scores has a mean of M = 85 and a standard deviation of s = 24. What is the estimated standard error of the t-distribution of sample means (i.e., of the t-test for a single sample)?

Answer 1

For the Standard error (SE), the main pieces of information you need are the standard deviation (s) and sample size (n).

SE=s/sqrt(n) = 24/sqrt(36) =24/6=4.
