What is an example of a continuous variable?

A continuous variable is one that can take on an infinite number of values within a given range. Such variables are often measurable quantities and are not restricted to distinct categories. Temperature serves as a prime example of a continuous variable because it can be measured in various degrees (such as Celsius or Fahrenheit) and can take on any value within a range, such as 20.5 degrees or 37.8 degrees.

In contrast, gender, favorite color, and job titles are categorical variables. They represent distinct groups or categories rather than measurable quantities that can vary continuously. This distinction underlines why temperature is the only option that exemplifies the characteristics of a continuous variable effectively.
