Hi,
I have a 3000+ row data set with two columns: StationID and DIN (dissolved inorganic nitrogen if anyone is curious). There are 166 stations, and I would like to get the mean DIN value of each station.
The data is set up like this:
StationID, DIN
1, 10.1
1, 12.2
1, 13.1
2A, 3.4
2A, 3.2
6012, 5.6
6012, 6.7
6012, 6.7
6012, 5.9
So, my main issue is that there are a variable number of DIN readings for each station, and the stations do not follow a pattern (some have letters, not consecutive numbers, etc).
Is there a good way of going about this?
Thanks
Edit. Thanks!
