And since we’re on the subject, systematic errors can’t be reduced by multiple trials , that’s random! • Alright, so these are the things worth points in abstract, 5 things, 2 point each: Purpose, Procedure summary, Numerical final results , Conclusion, Clarity. Anything more is not needed, anything less will cost points. Most of you seem to either forget the numerical results part or put every calculated number in abstract and leave out the main ones. Put the final numerical results in abstract! • Still problem with the golden rules… certain value and its uncertainty should match in decimal places. That’s always!...
