Millikan oil drop experiment

[lulu888]

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
