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 is a continuous random variable?

A continuous random variable is one which takes an infinite number of possible values. Continuous random variables are usually measurements. Examples include height, weight, the amount of sugar in an orange, the time required to run a mile. (Definition taken from Valerie J.

What is a continuous random variable give some examples?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.

What is the example of continuous variable?

Continuous variables can take on almost any numeric value and can be meaningfully divided into smaller increments, including fractional and decimal values. You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data.

Is gender discrete or continuous?

Variable Reference Table : Few Examples

Variable	Variable Type	Variable Scale
Gender	Discrete	Categorical
Gender as Binary 1/0 Coding	Discrete	Categorical
True/False	Discrete	Categorical
Phone Number	Discrete	Nominal

What is discrete random variables in statistics?

A discrete random variable has a countable number of possible values. The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1. A continuous random variable takes on all the values in some interval of numbers.

How do you describe discrete random variable?

Which is a discrete variable?

“A discrete variable is one that can take on finitely many, or countably infinitely many values”, whereas a continuous random variable is one that is not discrete, i.e. “can take on uncountably infinitely many values”, such as a spectrum of real numbers.

What is an example of a discrete random variable?

A discrete variable is a variable which can only take a countable number of values. In this example, the number of heads can only take 4 values (0, 1, 2, 3) and so the variable is discrete. The variable is said to be random if the sum of the probabilities is one.

What are some examples of continuous variables?

Some examples of continuous variables are measuring people’s weight within a certain range, measuring the amount of gas put into a gas tank or measuring the height of people. A continuous variable is any variable that can be any value in a certain range.

What are some examples of a discrete variable?

The following are examples of discrete random variables: The number of cars sold by a car dealer in one month. The number of students who were protesting the tuition increase last semester. The number of applicants who have applied for a vacant position at a company. The number of typographical errors in a rough draft of a book.

What are discrete variables?

A discrete variable is one that cannot take on all values within the limits of the variable. For example, responses to a five-point rating scale can only take on the values 1, 2, 3, 4, and 5. The variable cannot have the value 1.7. A variable such as a person’s height can take on any value.
