What type of qualitative data is categorized without a set order or sequence?

1. Internal data

2. Nominal data

3. Ordinal data

4. Data elements

The correct answer is: Nominal data

Nominal data is a type of qualitative data that is categorized without any specific order or sequence. It consists of distinct categories that represent different attributes or characteristics, and the categories cannot be ranked or ordered in a meaningful way. For instance, categories like colors (red, blue, green) or types of fruits (apple, banana, cherry) are examples of nominal data. Each category is separate and does not imply any sort of hierarchy or ranking, which is what distinguishes nominal data from ordinal data, where a specific order does exist. In contrast, internal data, ordinal data, and data elements do not correctly define this category of qualitative data. Internal data typically refers to data that is generated within an organization. Ordinal data involves a ranking or ordered relationship among categories, while data elements is a broad term that encompasses any distinct piece of data, which does not specifically describe the categorical nature of nominal data.
