Dear all,
Very simple question, but apparently uneasy to solve in R:
I have a sampling of a variable x: (3, 4. 5, 2, ...)
I want to know:
- the mean <x> -> mean(x)
- the uncertainty on <x> -> std.error(x) ? Or sd(x)?
- the standard deviation of x -> ?
- the uncertainty on the standard deviation -> ?
Anyone has an idea?
Thanks in advance,
regards,
Xavier
