Exploring systematic effects!

1. Determine the elementary charge from each of your applied voltages and plot the elementary charge as a function of the applied voltage. Fit the data with a straight line and determine the slope and its uncertainty. Is there a statistically significant trend? Should there be?
2. There is some variation in the radius of the polystyrene spheres, and a good experimentalist would quantify those variations to see if there is a measurable effect on their results. Find the average measured value of   and its standard deviation for each of your beads. Report the number of standard deviations between these individual values and the average for all beads. Comment on your results.
