**PsyDAG**, Friday, June 21, 2013 at 12:42pmb) mean = median = mode. See definition of median.

e) Z = (score-mean)/SD for raw scores. Answer wrong.

Z = (score-mean)/SEm for means. Answer wrong.

SEm = SD/√n = 4.6/√25 = 4.6/5 = .92

f) Use same process.

Use Table indicated in later post.

**sue7**, Friday, June 21, 2013 at 9:34pmI understand the median is when you arrange the numbers from small to large and it is the middle number. If I write down 1-69, middle number is 35 but the answer ask for it in four decimal places and that answer is wrong and (e) and (f). e I came up with 0.001 and (f) I am not really sure of.
