# Math Help - Area Under a Curve and Standard Error

1. ## Area Under a Curve and Standard Error

Hi all,

I am doing a research project for a physiology degree and have got a graph where I have figured out the area under the curve (AUC) using integration. However in journals where they analyse AUC they seem to have obtained a standard error (though some of these papers have used the trapezoid rule to calculate their AUCs). I was just wondering if it was possible (and if so how) to obtain a standard error from the AUC if you have calculated it by integration? I'll mention as well that the equation I integrated was for the curve of best fit for the data I have. Any help would be greatly appreciated. Thanks.

Hey Miico7.

I did a quick google search and got this (which looks very handy):
