Discrete Probability Distributions

What is a discrete random variable?

Back

A discrete random variable is a variable that can take on a countable number of distinct values, often representing counts or whole numbers.

Front

Give an example of a discrete random variable.

Back

The number of students in a classroom.

What is a continuous random variable?

Back

A continuous random variable is a variable that can take on an infinite number of values within a given range, often representing measurements.

Give an example of a continuous random variable.

Back

The height of a person.

Front

What distinguishes discrete data from continuous data?

Back

Discrete data consists of distinct, separate values, while continuous data can take any value within a range.

What is a probability distribution?

Back

A probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.

Front

What are the two main types of probability distributions?

Back

Discrete probability distributions and continuous probability distributions.

Front

What is the probability mass function (PMF)?

Back

The PMF is a function that gives the probability that a discrete random variable is exactly equal to some value.
