I will dedicate this day to studying Kurtosis. EDIT: As adressed by rolando2, it's hard to state that one is more important than the other in all cases, but I'm merely looking for some general insight. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? a skewed distribution has more severe consequences and should be avoided, whereas a small amount of kurtosis can be acceptable. For instance, robustness to these kinds of violations of normality partly depends on whether the group sizes are skewness and kurtosis.

This is not surprising since the kurtosis of the normal distribution is 3 :-) 1) Shapiro-Wilks test. b1 = g1 * ((1 - 1 / n))^1.5. The problem is that if you want to examine the effect of a highly skew distribution, you must also have a distribution with high kurtosis. In other words, skewness tells you the amount and direction of skew (departure from horizontal symmetry).
