The Deep Dive
Categorical data refers to information that can be divided into distinct categories or groups. Think of it like sorting your favorite ice cream flavors—vanilla, chocolate, and strawberry. Another example could be the types of pets, such as dogs, cats, and birds. These categories do not have a numerical value but simply represent different characteristics. Numerical data consists of values that are measurable and express a quantity. It can be further divided into discrete and continuous data. For instance, the number of students in a class (25) represents discrete numerical data. An example of continuous numerical data would be the height of those students, which can be any value within a range, like 150.5 cm.
