Variables are items that can change in value
The categorical variables are:
- Racial composition of a high school classroom.
- Color of cars in a mall parking lot
- The final letter grades of students in a class.
The numerical variables are:
- Points scored on a basketball game. (discrete)
- Heights of 15-year-olds. (continuous)
- Time it takes each student to complete a final exam. (continuous)
- Record of daily high temperature for the month of January in Akron. (continuous)
<h3>How to determine the type of the variables</h3>
Categorical variables are variables such as grades, and they are used in grouping collective variables of the same feature.
From the list of options, the categorical variables are: race, color and letter grades
On the other hand, numerical variables are variables that represent numbers, and they can take finite or non-finite values
When a numerical variable takes a finite value, then it is discrete.
If it takes non-finite value, then it is continuous
From the list of options, the discrete numerical variable is: points
While the discrete numerical variables are: Heights, Time and temperature
