Common questions
How are tied observations ranked?
Equal observations receive the average of the rank positions they occupy. The tool correlates these ranks; it does not use the no-ties shortcut formula.
How does Spearman rank correlation with ties work?
Rank each series with average ranks for ties, then calculate Pearson correlation between the two rank series.
