Q
how are uncertainties shown on a graph
A
as an error bar
2
Q
how do you calculate the percentage uncertainty in a gradient
A
draw the best lune of fit passing as close to all points as possible
draw the worst line of fit starting at the bottom of the first uncertainty and ending at the top of the last uncertainty
=best m - worst m / best m x100
or
= best y intercept - worst y intercept / best y intercept x 100
