What Are the Results of the Millikan Oil Drop Experiment?

Click For Summary
SUMMARY

The Millikan Oil Drop Experiment measures the charge of an electron using a mass of 1.57x10^-19 kg and various voltages (400, 457, 384, 369, 400, 355, 369, 436, 384, 369) across a distance of 0.1m in a gravitational field of 9.81 m/s². The discussion emphasizes the importance of comparing the experimental setup to Millikan's original design for accurate results. Participants are encouraged to share detailed data and images to facilitate better assistance and analysis.

Homework Statement
Hello, recently I have done the Millikan Oil Drop Experiment. I am required to determine my own fundamental charge and compare it with the accepted value of 1.6x10^-19. However, I am struggling greatly because I do not know how to do that. I did the experiment 10 times. The mass, gravity, and distance remained the same throughout. My voltages were different though. How do I calculate my own fundamental charge with this set of data? I am not sure how I would use the equation with 10 different voltage values.
Relevant Equations
q=mgd/v
mass: 1.57x10^-19 kg
voltages: 400, 457, 384, 369, 400, 355, 369, 436, 384, 369
distance: 0.1m
gravity: 9.81 m/s^2
