Which best describes your data?

 nominal
 A nominal scale is the grouping of data by some quality it possesses rather than by a rank. For example, you could group flowers by their color.

 ordinal
 On an ordinal scale, you may order discrete data in a hierarchical fashion with or without a quantitative measure. For example, you could order tree height by feet or as small, medium, and large.
