Percentage error

maximum uncertainty/ experimental reading x100

(maximum uncertainty is half the distance between the two smallest graduations on a piece of equipment).

∝

Proportional to

(One variable has a constant ratio to another variable. They change at the same rate, so the relationship between them doesn’t change).
