>Then why do they want ukraine to join nato if they don't want Russia touching a nato country
Think mirror.
They want to get up close to Russia to try and provoke Russia.
Why do you think they wanted Poland, Hungary, Lithuania and all those other eastern European countries to join NATO after the collapse of Soviet Russia and the reunification of Germany.
Spearman’s Correlation Explained
Spearman’s correlation in statistics is a nonparametric alternative to Pearson’s correlation. Use Spearman’s correlation for data that follow curvilinear, monotonic relationships and for ordinal data. Statisticians also refer to Spearman’s rank order correlation coefficient as Spearman’s ρ (rho).
