Detailed explanation-1: -Categorical data describes categories or groups. One example would be car brands like Mercedes, BMW and Audi – they show different categories. Another instance of categorical variables is answers to yes and no questions.
Detailed explanation-2: -Categorical variables describe characteristics of objects and can take one of a few possible values. The make of a car is a categorical variable, for example; it can be Toyota, BWM, Ford, or any other make. It’s easy to recognize a categorical variable by its values, which typically are strings and not numbers.
Detailed explanation-3: -Time is a continuous quantity. A person could drive for 10 minutes, or 10 minutes 30 seconds, or 10 minutes 10.23 seconds, etc. While drive times are often reported (or measured) in discrete units-for example, rounding to the nearest minute or second-the underlying random variable should be modeled as continuous.
Detailed explanation-4: -The models of the car represent categorical variable as they will be the models are the names which are not related to any numbers. Hence, the given variable is categorical in nature.
