Possible values of a variable Frequency or probability

3 Numerical Variables Location Scale Symmetry Tail Thickness (Center)
Location Scale Symmetry Tail Thickness (Center) (Spread) (Skewness) (Outliers) Order Median Interquartile Range Moment Mean Standard Deviation Skewness Coefficient Kurtosis Coefficient Coefficient of Excess Graphs Median and mean in boxplot Range and Interquartile range in boxplot Location of median relative to hinges Normal quantile plots Length of whiskers QQ Plots
