Which of the following data types would be classified as being categorical?

选项：

A. Discrete

B. Nominal

C. Continuous

解释：

B is correct. Categorical data (or qualitative data) are values that describe a quality or characteristic of a group of observations and therefore can be used as labels to divide a dataset into groups to summarize and visualize. The two types of categorical data are nominal data and ordinal data. Nominal data are categorical values that are not amenable to being organized in a logical order while ordinal data are categorical values that can be logically ordered or ranked A is incorrect because discrete data would be classified as numerical data (not categorical data). C is incorrect because continuous data would be classified as numerical data (not categorical data).
