Symbology- categorizing using mean/sum stats

Question

Hi all,

I have a large dataset that includes parameters for water quality data that extends back to the late 90's. I want to create a map that shows the average for certain parameters (1 map per parameter) for each point location over the last 10 years- I would like to put the averages into bins and color categorize them.

What is the best way to go about doing this? Is there a way to classify symbology based on the mean or other sum stats? I thought there was, but I can't seem to find what I am looking for.

Thanks!
