so. If I have a set of times and a set of distances, and I want to calculate the uncertainty of the velocities,
how do I do this?
My 'formula' looks like this
What would the uncertainty for the velocity be?
Question about dividing uncertainties? watch

Find the % uncertainty in both distance and time, then add the % uncertainties.
This gives the % uncertainty in the final value so convert it back to an actual uncertainty.
If you have a series of values it is normal to either draw a graph (if that is relevant) and find the gradient; or find the average of the values and use that.
