Homework Help: Percent error?

Posted by Emily on Sunday, January 13, 2008 at 6:28pm.

What is the formula for percent-error? It's either:

%error= (your value/accepted value)*100
or
%error= (accepted value/your value)*100

I'm pretty sure it's the first one, but I also heard it can go either way. I tried both ways but I end up with two different values. Which one is which?

Neither.
%error = [delta/accepted value]*100
delta = your value - accepted value

  Oh yeah. I was trying to remember it but I just couldn't get it straight. Thanks!
