IB2student Posted February 22, 2022 Report Share Posted February 22, 2022 Does percentage error really matter if percentage uncertainty is already included in extended essay and should it be put in appendix or in the main body? Reply Link to post Share on other sites More sharing options...
aposded Posted February 22, 2022 Report Share Posted February 22, 2022 YES. Percentage error is quite different to percentage uncertainty. Pecentage error shows how far you were from the literature value, while perentage uncertainty shows in what range your experimental value actually is. If the literature value falls within your percentage uncertainty, then you can conclude that you had no systematic errors (assuming 100% yield). HOWEVER, you do still need to mention that.
