Draft Report on European Baccalaureate 2020

At the same time the striking difference that characterised the distribution of this year's
preliminary marks when compared with the final marks of the last five years has been
reasonably moderated, preserving the credibility of the European Baccalaureate.

The visual impression is confirmed repeating the chi-squared test with the moderated
marks: its results show that the statistical difference between the distributions of the
final marks of the past years and this year's moderated marks has been considerably
reduced.

The comparison of cumulative graphs of the past five years and of this year helps in
understanding that, reasonably, this year's students have not been negatively
affected, compared with those of earlier years.
