Nominal data refers to categories or names that do not have a specific order or ranking. It is used to label variables without providing quantitative value. In this context, gender identification serves as an excellent example of nominal data because it classifies individuals into categories, such as male, female, or non-binary, without implying any hierarchy or numeric value.

In contrast, patient ID numbers, while they can serve as identifiers, are more of a categorical variable used for data management rather than representing a nominal level of measurement since they often include a sequential element. Blood pressure readings and temperature records are examples of continuous data that are measured on an interval or ratio scale, involving numerical values where one can calculate averages and determine order. Therefore, gender identification stands out as the clear representative of nominal data in this question.
