It is an ordinal scale and shows merely the order of rating on the scale.The rank position of an individual on a given reference distribution, stated in terms of what percentage of the group the individual equals or exceeds .

The Z-score is a quantile, and takes values from −∞ to ∞ . The cumulative percentile is bounded from 0 to 1. When the distribution is known, the percentile can map 1-1 to any observation for any distribution, whereas the Z-score only has this property for normally distributed data; hence these summaries are equivalent when normality is met.
