Correlation quantifies the connection between variables, crucial for research across disciplines.
Non-parametric correlations like Kendall Tau-b and Spearman's rho are vital when data isn't normal.
Kendall Tau-b is robust, excelling in small samples with strong correlations and outliers.
Spearman's rho is sensitive, ideal for small samples and detecting weak correlations.
For large datasets, Kendall Tau-b's reliability outshines Spearman's rho.
Kendall's Tau-b offers more accurate correlation measures in datasets with outliers.
Kendall Tau-b accurately reflects strong variable associations, regardless of sample size.
Choose Kendall Tau-b for robust analysis; Spearman's rho for simpler, preliminary studies."
Sample size, outliers, and correlation strength guide the choice between Kendall and Spearman.
