WebIn the Spearman correlation analysis, rank is defined as the average position in the ascending order of values. So when two runners tie for second place, this results in one runner with a rank of 1 (first place) and two runners each with a rank of 2.5. The next runner who have a rank of 4. If tied ranks occur, a more complicated formula is used ...
