## Basics of Statistics – Continuous Probability Distribution

Viewer Rating [Total: 0    Average: 0/5] You must sign in to voteLet us start today’s topic on uniform probability distribution (I will discuss on continuous dist today). Now, the concept comes in two forms: discrete and continuous. If I toss a coin then there are two possible outcomes: Head and Tail. If I roll … Read moreBasics of Statistics – Continuous Probability Distribution

## Basics of Statistics – Binomial Distribution

Viewer Rating [Total: 1    Average: 5/5] You must sign in to voteToday, I would like to extend my previous topic on discrete probability distribution with the concept of Binomial Distribution. A binomial distribution is a specific probability distribution. It is used to model the probability of obtaining one of two outcomes, a certain number of times … Read moreBasics of Statistics – Binomial Distribution
