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. A positive value means the distribution is positively skewed. Repeated measures ANOVA: what is the normality assumption? See 'Details'. The score distribution of the subscales was evaluated using skewness and kurtosis statistics, the KolmogorovSmirnov (KS) test, and plots (normal probability plots, normal quantile plots, and histograms). WebThe usual processes in the statistical assessment of a data set are: & screen the data for outliers or blunders; & plot the data to detect asymmetry and tail weight; & calculate the indices of sample shape (i.e., skewness and kurtosis); & perform test(s) of Normality; & if the data is Normal use parametric statistics for further analysis; D. N. Joanes and C. A. Gill (1998). Arguments passed to or from other methods.
