Hi, I was sitting through a presentation of some research yesterday about the results of a pilot study where a control group was compared with a treatment group and I found that I was rather confused about the use of the term standard error. The researcher appeared to be saying something about having too small a standard error was not a good thing.
Could someone please explain or link me to a page where I could get some detailed information about use of the standard error. I think that it is a measure of the standard deviation of the sample means, but this doesn't appear to be the context that was used (from my understanding). When is it good to have a large standard error? When is it good to have a small standard error? Do these answers differ for different tests and different experimental designs?
