Final answer:
The set of possible values for a given attribute is known as the domain of the attribute.
Step-by-step explanation:
The set of possible values for a given attribute is known as the domain of the attribute. In mathematics, the term 'domain' is commonly used to describe the set of inputs or independent variables of a function, but it can also be applied to other contexts.
For example, if we have an attribute X representing hair color, the domain of X could be {black, blond, gray, green, orange}. These values are all possible options for the attribute 'hair color'.
It's important to note that the specific value x of the attribute X can only be determined after performing an experiment or observation.
