Question

how do you calculate the standard deviation if your given the standard error

Answer 1

if I remember correctly its

SD = SE / n - 1 for pop
SD = SE / n for sample

Answer 2

so if i have this info group 1: n=9, mean= 59 and SE=7 and group 2: n=11 mean=32 and SE=10 how do i know which is populatinon or sample

Answer 3

well what exactly is the question asking you to do?

Answer 4

what are the two sample standard deviations

Answer 5

Do it separately for each info group:

standard error of mean = SD / sqroot ( N )

re arrange for SD = standard error.. * sqroot ( N )

Answer 6

ignore my first formula btw

Answer 7

to make sure its \[SE \times \sqrt{n}\]

Answer 8

yep

Answer 9

thanks
