The χ² goodness-of-fit test is appropriate for nominal or categorical data, but not just ordinal data. This means that the data can be divided into categories but the categories do not have a natural ordering. The other assumptions of the test include nonparametric nature, minimum expected frequency in each cell of 5, and random selection of sample.
