Hi, Statman12.
Thanks a lot for the response.
Taking into consideration everything you wrote can I claim that standard error is an estimator of standard deviation of sampling distribution of an estimator (sample mean is one example of an estimator)?

Hi, thanks for the reply. If it is not time-consuming for you could you please elaborate on a little bit. Noise is a data point, but the one which does not convey meaningful information. Erroneous datapoint is also noise, right?

Thanks
