Conclusion and Evaluation (CE) 1
Conclusion
- State whether your graph supports the theory. E.g. Is the relationship between the quantities linear? This is only true if the line touches all error bars, don’t say it is if it isn’t.
- Are there any points on the graph that appear to be due to mistake (outliers), maybe it’s best to remove these and plot the line again?
- Normally the data will be arranged so that the gradient will give you some value (e.g. “g”) calculate this value from the gradient.
- Calculate the uncertainty in this value from the steepest and least steep lines.
- Compare your result with an accepted value, say where this value is from and quote uncertainty if known.
