What is the term for a collection of data values that can be of different types?

The term for a collection of data values that can be of different types is commonly referred to as a "List Object." In many programming languages, a list is a versatile data structure that allows for storage of various types of data within the same collection. This makes it particularly useful for applications where you might need to group different elements together, such as strings, integers, and other objects, into a single structure while maintaining order.

In contrast, arrays are typically collections of data values that must all be of the same type. Sets also do not allow for repeated values and are generally of a single type, focusing on uniqueness rather than mixed data types. Tuples, while they can store multiple data types, are usually immutable, meaning once created, they cannot be changed. This immutability is a key distinction that separates tuples from list objects. Therefore, the appropriate term that encapsulates the idea of a collection of mixed types is indeed a "List Object."
