IMO the data is good, the analysis well designed, the statistical instruments appropriate for their intended purpose, and the results meaningful. Any discussion about variability, skewness or kurtosis is supurfulous -- you don't have to beat the data to death to answer the question. Further analyses of the information would be overkill and likely not alter the relative outcomes significantly. Excellent job kam and thanks for taking the time to share your results! Just my 2 cents worth.
