Variables: Discrete and Continuous Variables
Understand the Problem
The question is asking for an explanation or information about discrete and continuous variables, which are fundamental concepts in statistics and data analysis. Discrete variables are those that can take on a countable number of values, while continuous variables can take on an infinite number of values within a given range.
Answer
Discrete variables are countable. Continuous variables can take any value within a range.
A discrete variable is a variable that takes on distinct, countable values. In contrast, a continuous variable can take any value within a range, with an infinite number of possible values within that range.
Answer for screen readers
A discrete variable is a variable that takes on distinct, countable values. In contrast, a continuous variable can take any value within a range, with an infinite number of possible values within that range.
More Information
Discrete variables typically result from counting, such as the number of students in a class. Continuous variables typically result from measuring, such as a person's height.
Tips
Avoid confusing discrete and continuous variables based on data representation; instead, focus on it being countable or measurable.
