Here is some information from ASHRAE HOF:
Simple design conditions were obtained by binning hourly data into frequency tables, then deriving from the binned data the design condition having the probability of being exceeded a certain percentage of the time. Mean coincident values were obtained by double-binning the hourly data into joint frequency matrices, then calculating the mean coincident value corresponding to the simple design condition.
The use of the word "mean" is to imply that a mathematical mean, or average, is used.
