This is the crucial difference with nominal data. Ordinal data is data which is placed into some kind of order by their position on the scale.

For example, they may indicate superiority. Because this is ordinal data, the assumptions that the data follow a normal distribution will be violated. Given that the assumption of normality is violated, a typical paired t-test in this situation would at best lack sensitivity, and at worst provide spurious estimates. If we cannot be sure that the intervals between each of these five values are the same, then we would not be able to say that this is an interval variable, but we would say that it is an ordinal variable. However, in order to be able to use statistics that assume the variable is numerical, we will assume that the intervals are equally spaced. We also looked at how ordinal data types can overlap with the discrete data types.
