Results and Discussion




Most important section of the report
Results should be explained in text and presented in
graphical form
Trends in data should be justified with physical
arguments
Experimental results should be compared to theory
whenever possible



Calculate a % error
If discrepancies exist, why?
Read pages 5 & 6 of Writing style and standards in
undergraduate reports
Conclusion


