What type of variable is commonly used to represent categories, such as the names of different fruit?

• A. Ordinal Variable
• B. Continuous Variable
• C. Nominal Variable
• D. Discrete Variable

Answer: (C)

The correct choice is a variable that represents categories, such as the names of different fruits, which is a nominal variable. Nominal variables are used to label variables without implying any quantitative value. They strictly categorize data into distinct groups where no order or ranking is necessary. For instance, different types of fruit like "apple," "banana," and "cherry" are simply categories with no intrinsic ranking among them. In contrast, ordinal variables involve categories that have an inherent order or ranking, such as "small," "medium," and "large." Continuous variables refer to numerical values that can take an infinite number of ranges within a given interval, such as height or weight. Discrete variables involve countable categories, like the number of apples in a basket, which are distinct but still not suited for categorizing names of items without an order. Thus, the characteristics of a nominal variable make it the most appropriate classification for representing categories like fruit names.
