k = number of AB comparison units
Mean difference = the mean of the differences calculated by subtracting the value of the second Indicator from the value of the first Indicator for each AB comparison unit
Mean absolute difference = the mean of the absolute differences between the two Indicators for each AB comparison unit
Min, Max: the minimum and maximum values of the differences
