Resource summary

Question	Answer
How do you calculate percentage uncertainty?	(absolute uncertainty/average measurement) x 100
What is absolute uncertainty?	The smallest interval that the measuring equipment you're using can measure (eg. a ruler can measure to the nearest mm, so the absolute uncertainty is 0.001)
How do you calculate percentage difference?	((accepted value - experimental value) / accepted value) x 100
