The Spearman rank-order correlation coefficient is appropriate for ordinal data because it is based on the ranks of the data rather than their actual numerical values. This makes it applicable for studying relationships between variables measured at an ordinal level of measurement. It cannot be used for nominal data because nominal variables do not have a natural ordering, and it is not appropriate for interval or ratio data because it assumes that the intervals between values are equal, which may not be the case for these types of variables.
