WebAn alternative name for the Spearman rank correlation is the “grade correlation”;[6] in this, the “rank” of an observation is replaced by the “grade”. In continuous distributions, the grade of an observation is, by convention, always one half less than the rank, and hence the grade and rank correlations are the same in this case.
