I'm looking for the Planck's constant using the data I gathered for the potential difference and frequency. Then, I drew a best fit line and find its slope. My problem is, I have to find uncertainty but I don't have any idea if I will include it in the final answer for the Planck's constant? Also, how can I find the percentage error with the uncertainty?

This stuff always confuses me.

Maybe the physics section will help more, since this is common in labs!

Oh yeah! lol thanks for telling me that this is a wrong section O_O

I can used derivatives to find the formula for the estimated error, but I can't think of how to find uncertainty at the moment.... Unless they're the same thing, I don't know!

No problem! :)
