It would be interesting to do a rank-sum analysis comparing each pair of encoders. Although the numeric values assigned by the listener seem like legitimate statistical data, the only real value is whether or not a listener ranked one encoder higher or lower than another.

... whether or not a listener ranked one encoder higher or lower than another.

I thought that (Garf, correct me if necessary) this information is reflected in the p-value tables and whether or not the confidence intervals of two coders overlap.

Interesting results. I guess I have to add Sample20 to my standard test set at work...

Yes, the ANOVA test is using Friedman which is ranking the codecs. The graphs seem to be built based on parametric analysis of the test results as if they were normal data.
