Average temperature: Difference between revisions

This offers an alternative to the simple mean of the highest and lowest temperatures of the day, and can give a 'better' average in cases where the high or low temperature occurred for a relatively short period, so could skew the simple average. To compare the two, select ''This period'' from the '''view''' menu and by default it will show both the integrated mean and simple mean temperatures for yesterday when you click '''Update display'''. Although average temperatures are not available as webtags, the integrated mean temperature for each day is output to the monthly NOAA style report, and the highest and lowest integrated mean temperature for each month are output to the annual NOAA style report.▼

Note that statistically, a median temperature could be used, this would require holding all the individual measurements for a day, ranking them in order of magnitude and quoting the central value in that list (again this means extreme values have less skewing effect) - Cumulus does not retain the every minute individual values and cannot calculate median. If you wanted to compare daily median and daily mean, you would need to analyse the monthly log file with an external package.▼
