Uncertainties in forces and weight?

Hi, I am working with Friction. We had a task to determine the coefficient of kinetic friction. We did an experiment where we weighted a block and used a newtonmeter to determine its force.

The thing is that the balance that we weighted the block with had an uncertainty and the newtonmeter had an uncertainty as well. This is supposed to be displayed in a table and graph. But I am very unsure how to put it there.

The coefficient of kinetic friction can be determined by μk= (Ff (N))/(mg(N)), as the normal force and mg are the same in this case. But I am very unsure how to add the uncertanties to the weight as well as to the force, and label them on the graph. Could someone please propose and idea?
