What are examples of discrete variables and continuous variables?
Difference between Discrete and Continuous Variable
| Discrete Variable | Continuous Variable |
|---|---|
| Examples: Number of planets around the Sun Number of students in a class | Examples: Number of stars in the space Height or weight of the students in a particular class |
What are the real life examples of discrete random variable?
Examples of discrete random variables include:
- The number of eggs that a hen lays in a given day (it can’t be 2.3)
- The number of people going to a given soccer match.
- The number of students that come to class on a given day.
- The number of people in line at McDonald’s on a given day and time.
What is a real life example of a continuous variable?
Another example of a continuous random variable is the weight of a certain animal like a dog. This is a continuous random variable because it can take on an infinite number of values. For example, a dog might weigh 30.333 pounds, 50.340999 pounds, 60.5 pounds, etc.
How do random variables apply to real life situations?
A typical example of a random variable is the outcome of a coin toss. Consider a probability distribution in which the outcomes of a random event are not equally likely to happen. If the random variable Y is the number of heads we get from tossing two coins, then Y could be 0, 1, or 2.
What is the difference between continuous variable and discrete variable?
Discrete and continuous variables are two types of quantitative variables: Discrete variables represent counts (e.g. the number of objects in a collection). Continuous variables represent measurable amounts (e.g. water volume or weight).
What is the difference between continuous and discrete random variables?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.
What are discrete variables examples?
A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar. number of heads when flipping three coins. students’ grade level.
