Which of the following is NOT a type of variable?

Datasets are typically not classified as a variable type in the same way that Booleans, Strings, and Integers are. In programming and data analysis, a variable is a storage location identified by a name that can hold different values over time.

Booleans are variables that can hold one of two values: true or false. They are frequently used to represent conditions in logic operations. Strings represent sequences of characters and are commonly used for text data. Integers are whole numbers without a decimal component, used for counting, indexing, or any mathematical operations where fractional values are not required.

Datasets, however, often refer to structured collections of data, which could include various types of variables, but the dataset itself is not a type of variable. It can contain multiple variables, each potentially of different types (including Booleans, Strings, and Integers), but is considered more of a data structure or container than a variable type. This distinction clarifies why datasets do not fall under the same classification as the other options listed.
