Hi Ricardo,
Average Min —The unweighted average of the minimum values of all periods.
Average Max—The unweighted average of the maximum values of all periods.
Mean—A weighted average, calculated as follows: (tv1 + tv2 + tvn...) / dp where tv is the total of all values for a period, and dp is the total count of data points for all periods. This gives greater weight to periods with more data points.
Absolute Max—The actual largest or highest single value across all periods.
Absolute Min—The actual smallest or lowest single value across all periods.
Regards,
Matt
