Is it suitable for academic or professional research?

Absolutely. The skill follows scientific best practices by calculating not just p-values, but also effect sizes and confidence intervals to provide a complete picture of statistical significance.

Which Python libraries are required for this skill?

The skill utilizes industry-standard libraries including Pandas for data manipulation, NumPy for numerical computations, and SciPy or Statsmodels for advanced statistical testing.

Does it provide visual data verification?

Yes, it includes patterns for visual assumption checking, such as generating and saving Q-Q plots to verify normality through Matplotlib integration.

Can this skill handle data that isn't normally distributed?

Yes, it includes robust non-parametric alternatives such as the Mann-Whitney U test, Cliff's Delta for effect size, and Permutation tests for complex data distributions.

How does the skill handle memory constraints during analysis?

It features dedicated memory management patterns, including tracking DataFrame size in MB and implementing explicit garbage collection for large-scale data processing.
