# Uncertainty and averages.

## Homework Statement

In my lab we are doing Franck Hurtz experiment with heated mercury and electron beams. We already took data but i need a little help. I have the locations of the minimums A B C D and E, and each point has it's own uncertainty. a b c d and e. What i needed to find was the difference between each min and the next, so A-B, B-C... and then find the average of each these differences. I don't know how to do the uncertainty for my calculations.

## Homework Equations
