Stantard Error was used commonly in report of science/physics experiment.

the result was always written as x + (delta)x,

where (delta)x was called standard error.


The physical meaning of standard error is:

if the measurement was repeated, there is 68.2 % that the result was be measured in the range x + (delta)x

The sentence--

"In other words the standard error is the standard deviation of the sampling distribution of the sample statistic (such as sample mean, sample proportion or sample correlation)."

--is incorrect. The SE is an *estimate* of the SD of the sampling distribution. I'm changing this sentence to make it correct in the article.

[edit] standard error an estimate

The sentence--

"In other words the standard error is the standard deviation of the sampling distribution of the sample statistic (such as sample mean, sample proportion or sample correlation)."

--is incorrect. The SE is an *estimate* of the SD of the sampling distribution. Someone should change this sentence (and all other instances of the same mistake) in the article.
