WebAn absolute skew value of greater than 2 or a kurtosis (proper) above 7 (4 for excess kurtosis) would indicate the sample distribution is non-normal. Most statistical packages give you values of skewness and kurtosis as well as their standard errors. An extremely closely related question concerning the two-sample t-test - effectively a one-way ANOVA with two levels in the factor - is, I agree with @rolando2: "skewness is worse than kurtosis" or vice versa is a rather vacuous statement without mentioning the degree of skewness/kurtosis.

In his review of kurtosis, DeCarlo (1997) suggested the exact opposite, that skew was more important in ANOVA and other tests of equality of means. I.e. Positive skew indicates that the tail is on the right side of the distribution, which extends towards more positive values. Here again, we calculate the numerator first.
