I have some data to calculate the photoelectric effect, and with my measurements I have made a graph using the least square fitting for voltage vs. frequencies. If I have an error of(adsbygoogle = window.adsbygoogle || []).push({}); xfor all voltages (V) andyfor all frequencies f.

How do I calculate the error of the valuesmandaif my fitting isVo=mf +a?

If needed here I post the data I have

The slopemish/e= 4.59*10^(-15)V/Hz

and the constantais the working function in electronvoltsW/e=2.11eV

And the errors

for voltages arex= 0.05V

for frequenciesy= 2*10^11

and I am using 5 data pairs.
