Scatter plot of the MAD (a, c) and (b, d) statistics extracted from the 2BL test of each precinct as a function of the number of municipalities in each precinct (2015 results are shown in (a, b) and 2016 ones are shown in (c, d), with no obvious differences). In the case of MAD, we find a weak negative correlation as expected, but this correlation is not enough to explain the systematic nonconformance to 2BL. In the case of , the effect is quite the opposite, and nonconformance is stronger as the size of the precinct increases, thereby suggesting that nonconformance to 2BL at this level of aggregation is a genuine result and not a spurious effect of finite size statistics.
