We now measure the amount of correlation (W) among the judges: W = 1.0 => perfect correlation, W = 0 => no correlation
We also provide a probability measure that this correlation is due to chance
In this case the correlation is = 0.1384
Probability that correlation is due to chance = 0.3552
We compute the correlation of each taster with the average ranking of the oth- ers. 1.0 => perfect correlation, 0 => no correl., -1.0 => total disagreement

Comments:
This was a most memorable tasting. We have never before had another tasting with such a star-studded cast of characters. We might characterize is as a historic tasting and it was a privilege to taste such great wines from the same vintage. The Leroy wines turned out very well and held their own against the group consisting of the Romanëe Conti and Comte de Voguë wines. They all still tasted young and we may note that the two most famous Richebourgs underperformed and that the La Tache did not rise above the flock. Some tasters detexted a touch of oxidation that may have affected the overall evaluations. All these wines were characterized by the sweetness for which the greatest Burgundies are known.
