In a short essay, compare and contrast the categories of mutually exclusive and collectively exhaustive

What will be an ideal response?

Nominal scales are used for classification purposes. They serve as labels for classes or categories. The classes are mutually exclusive and collectively exhaustive. Mutually exclusive means that there is no overlap between classes; every object being measured falls into only one class. The objects in each class are viewed as equivalent in terms of the characteristic represented by the nominal scale. All objects in the same class have the same number, and no two classes have the same number. Collectively exhaustive means that all the objects fall into one of the classes. For example, the numbers 1 and 2 can be used to classify survey respondents based on sex or gender, with 1 denoting females and 2 denoting male. Each respondent will fall into one of these two categories.
