What is the difference between SE(Standard Error) and SEM(Standard Error of Mean - (May/01/2006 )

when I add Error bar on my statistics, I am not sure which one I should use, SE or SEM? Is it possible to use Excel to do SEM?

see http://mathworld.wolfram.com/ and ask math world - the accuracy will probably be better and you should have more confidence that you are getting the correct information.

Enjoy.
