A percentage yield greater than 100% has been reported in a scientific paper you are assigned to read. What would be a reasonable explanation for this? The product was measured more than once. It must be a typographical error since yields can't exceed 100%. A lack of training of the professor who published the study. Small measurement errors could have caused this to occur.
