Its about random radioactive decay. I have a histogram showing the number of counts recorded in 3 second intervals and I've drawn the Poisson Curve on the same graph.

I have a graph for 50 intervals and one for 100 intervals and I need to analyse how well the data agrees with Poisson Distribution....and see if the 100 interval graph is any better than the 50 intervals.

2. Relevant equations

n/a

3. The attempt at a solution

I was thinking I should add up the differences between each bar on the histogram and the curve...subtracting the ones under the curve and adding the ones above. I'm sure this has a name in statistics and I need to know what it is - that's basically my question.

What is the name of this graph analysis/statistics thing that I'm using? Or should I be doing something else???

I posted this in Physics first but I think it might be better in here...I just wanna know what to look up in order to find out how to analyse my graphs!..
