Data are interpreted through mean (accuracy) and standard deviation (precision) as we have seen in previous videos. But there is one more parameter that we can use to estimate precision; standard error, more commonly called standard error of the mean. It's a quick and easy value to determine and is a very useful parameter, so here we look at how it's defined and how to calculate it. Oh, and I give you a handy shortcut to calculate it too.

*The REALLY keen viewers among you will notice I say add the terms together when I describe the SEM equation and I should have said subtract ;) Trust me, the equation as presented in the video is correct!
