Statistical Tests (src.statistical_tests)

Thin, dict-returning wrappers over SciPy so results are JSON-friendly:

• hypothesis_tests: t-test, chi-square, ANOVA, correlation, normality battery.
• nonparametric: Mann–Whitney U, Wilcoxon signed-rank, Kruskal–Wallis, Friedman.
• descriptive: describe, quantile_summary, outlier_detection, correlation_matrix.

from probviz.statistical_tests import t_test, describe
print(t_test([1, 2, 3], [1, 2, 4]))
print(describe([1, 2, 3, 100]))
