Resolved: Standard error in the exam
I am a little confused about the standard error calculation in Sample Dataset 2 spreadsheet. According to the solution, first it is necessary to calculate de standard deviation of the sample formed by the sample means. But wouldn't that actually be the standard deviation of the sample itself that should be calculated and not of the sample formed by the sample means in the sheet?
Thank you

Hello Eduardo!
Thanks for reaching out!
Don't be confused by the wording "sample means" here. All you have to do is calculate the standard deviation of the sample. In this case, sample is represented by "means of data".
You are right in your approach.
