Understanding Random Variables
Understanding Random Variables
Random variables help us understand and calculate the probabilities of different events. Learn how to use random variables in this lesson.
The Discrete Uniform Distribution
The Discrete Uniform Distribution
The discrete uniform distribution is a simple probability distribution that can be used to introduce important concepts that apply to any distribution. Learn how to use it in this lesson.
The Continuous Uniform Distribution
The Continuous Uniform Distribution
A continuous distribution differs slightly from a discrete one. In this lesson, we'll learn about these differences using the uniform distribution.
The Binomial Distribution
The Binomial Distribution
The binomial distribution is useful for events that have two possible outcomes. Learn how to calculate probabilities from the binomial distribution in this lesson.
Introducing The Normal Distribution
Introducing The Normal Distribution
The normal distribution is one of the most common distributions in statistics. This lesson introduces the distribution and its fundamental properties.
Using the Standard Normal Distribution
Using the Standard Normal Distribution
The standard normal distribution is a commonly used example of the normal distribution. Learn how to use it in this lesson.
Introducing the t-Distribution
Introducing the t-Distribution
The t-distribution is an alternative to the standard normal distribution that can be used when you have data from a sample and not a population. Learn about this distribution in this lesson.
Understanding the Chi-Squared Distribution
Understanding the Chi-Squared Distribution
The chi-squared distribution occurs when we combine several standard normal random variables. Learn about the main properties of the distribution in this lesson.
The F Distribution
The F Distribution
The F-distribution occurs when we combine several standard chi-squared random variables. Learn about the main properties of the distribution in this lesson.
The Triangular Distribution
The Triangular Distribution
The triangular distribution is a simple probability distribution based on three possible values. Learn how to calculate probabilities from this distribution in this lesson.
The Lognormal Distribution
The Lognormal Distribution
The lognormal distribution is a variant of the normal distribution that can be used when your data is not suited to the normal distribution. Learn how to use it in this lesson.
The Poisson Distribution
The Poisson Distribution
The Poisson distribution can be used to model the number of times some event occurs in a specified timeframe.
