Percent error?
What is the formula for percenterror? 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

percent error formula= experimental value accepted value / accepted value * 100% % error = 0.846 g/mL  0.78948 g/mL / 0.78948 g/mL *100% = 7.31 % Is 7.31% correct or was there a calculation mistake?

How do you find Absolute error and how do you find relative error? Absolute error is the difference between the experimental value and the actual value. Relative error, usually expressed as a percent, is the error relative to the

Find the absolute and percent relative error for each calc. b) 81.5 (+/ 0.5) x 40.2 (+/ 0.2)/ 21.8 (+/ 0.2) my answer for absolute error was 150. +/ 200, which is outrageous. Can someone show how they would do it so I can

To calculate the percent error you would use the error in measurement divided by accepted value times 100 correct? So for an experiment in which you had to find the concentration of a dye in a powdered drink solution, to find the
