What do the numebrs mean?

If the error above is POSITIVE, then it means that the analysis temperature is HIGHER than the reported temperature. This means that your sensor is reading COLDER than expected.You can look at those for comparison purposes. The average difference between your station and each station below is listed as well. This may allow you to detect local stations which are erroneous. You can also use these numbers to adjust your instruments -- especially if a number of ASOS stations have similar differences to your station.

I understand and know that. I had read that on my QC page. That means nothing to me though if I am not sure of which set of numbers I should be paying attention to. So what I am asking is which numbers should I be focusing on and which of those numbers is what.
So for example on my 7 day here are the numbers. Which of these should I be paying attention to. which is my station?
24 hours Day time Night time
Average temperature error -2.2 °F -2.9 °F -1.8 °F
Error standard deviation 1.3 °F 1.3 °F 1.0 °F
Worst average temperature error -2.7 °F -3.7 °F -2.4 °F
Worst standard deviation 1.4 °F 1.6 °F 1.8 °F
I have 4 sets of numbers above and do not know what is what and what I am looking at or should be paying attention to. I know it is comparing it to other stations but which is mine and which are the numbers are those it is comparing it to? Their are positive and negative numbers. So unless I know what I am looking at I am not sure what it is doing.

You may want to contact Russ at CWOP and ask him. He may be able to help you and give you the detailed info you are looking for.

I have emailed him over a week ago and I haven't received a response yet. I am just trying to find out with those four sets of numbers which one I am suppose to be more focused on that is my station? Anyone know?

Hi,
I've asked the same question on two forum with no answer that I can understand. Googling for "standard deviation" really confused me so I'm hoping for a clear understandable ( to me ) answer somewhere.
I have looked at the WXQC mailing list but did not register and post the question there, but I think that may be a good place to try.
Good luck with this question. If you find something, please post it here.
Regards, Bob
