Homework Statement
I'm given data for 5 years of number of accidents. The problem asks about the Variance of the empirical distribution of the number of accidents per year.
Homework Equations
The Attempt at a Solution
I'm not sure what an empirical distribution means. I wasn't able to find a good example or definition online. At first I went and just found the average (total accidents / 5) and then used that to find the 2nd central moment, or the variance. I'm not sure if that is the correct way to do it. The part that confuses me is the empirical distribution part of it. If someone could clarify if I'm on the right track or what an empirical distribution is, that'd be great. Thanks for any help.
