Uncertainties
Tables old method
• (max – min)/2• 1 sf
New method 1
• Standard deviation• 2 sf
New method 2
• (max – min)/N• 2 sf
Old method
• g = 9 ± 3 m s¯²
New method 1
• g = 9.4 ± 1.5 ms¯²
New method 2
• g = 9.4 ± 0.3 ms¯²
Now also OK
• Propagation through calculation but no graph• Curves• Other• Tick lists are out• Don’t let uncertainties spoil a good practical
