Hi R user, Can we calculate sample size when only mean and SE are given? Let say one example, I have mean with SE is 0.54+-0.0517 (mean+-SE). Is there any way to find the samples (sample size n) in that condition in R? i think this question is not related to R, I hope you won't mind. Thanks [[alternative HTML version deleted]]
You are right, your question is not related to R, so not appropraie here. I pasted your question into google instead, and got all sorts of suggestions, ncluding https://www.isixsigma.com/tools-templates/sampling-data/how-determine-sample-size-determining-sample-size/ Sarah On Thursday, April 14, 2016, Marna Wagley <marna.wagley at gmail.com> wrote:> Hi R user, > Can we calculate sample size when only mean and SE are given? > Let say one example, I have mean with SE is 0.54+-0.0517 (mean+-SE).

But the answer (short, long or indifferent) to your question is No. And furthermore, don't be silly. SE = s/sqrt(n). If you knew s you could solve for n, but you don't. Full stop. There's an end to it. Any further mucking about is unproductive wishful thinking. cheers, Rolf Turner P. S.

Has anyone ever heard of or used Microsoft R server? Does the product work? What
are requirements for running it? How much does it cost and is it supported by
the R community?
Thank you,
John
