Data Analysis
- Present tables of your measured data, with calculations for
and 
. Include a column with the direction that the bead is moving. Please make separate tables for the different applied voltages. Include the uncertainty in your measured values, which likely also depend on the calibration factor and its uncertainty. - Present a table of the average values of and for each bead at your preferred (i.e. best) applied voltage, and use those values to calculate the charge on each bead.
- Look at the difference between pairs of charge measurements taken with the same applied voltage. Ideally, these differences would come in integer values of some elementary charge value. Look at the ratio of as many pairs of your charge measurements as you can without losing your sanity. Can you deduce an integer of charge? Quantifying the uncertainty in this type of analysis can be difficult and subjective. Do your best to estimate an uncertainty and give your reasoning for it.
- Compare your value to the accepted CODATA value.
