"The tool for analysing semantics is logic, not statistics." #readingToday
There is no way to go forward characterizing the uncertainty with which the measurements were made, nor what it may be attributable to. It is hard to say whether one category is right or wrong, or average, because it is an entirely subjective semantic result. The question was phrased in semantic choices, which are not easily understood, measured or assessed. The tool for analysing semantics is logic, not statistics.
