A rank is a consecutive number assigned to a specific observation in a sample of observations sorted by their values, and thus reflecting the ordinal relation of the observation to others in the sample. Depending on the order of sorting (ascending or descending), the higher ranks represent the higher values [i.e., ascending ranks, the lowest value is assigned a rank of 1, and the highest value - the "last" (highest) rank] or higher ranks represent the lower values (i.e., descending ranks, the highest value is assigned a rank of 1). See Ordinal Scale, Coombs, 1950, see also Tied Ranks.
