%description
Comparing two independent or paired groups across a range of descriptive
statistics, enabling the evaluation of potential differences in central
tendency (mean, median), dispersion (variance, interquartile range), shape
(skewness, kurtosis), and distributional characteristics (various
quantiles). The analytical framework incorporates parametric t-tests,
non-parametric Wilcoxon tests, permutation tests, and bootstrap resampling
techniques to assess the statistical significance of observed differences.
