What is normal distribution? A normal distribution can assume values that are infinite and uncountable. For example, the time it takes a student to commute from home to a university could be a normal distribution. Suppose that 15 minutes is the minimum time and 60 minutes is the maximum time it takes all students to commute from home to the university.
Let x be the time it takes a randomly selected student to commute from home to the university. Then, x can assume any value in the interval 15 to 60 minutes. This interval contains an infinite number of values that are uncountable.
In this unit, we will first learn about continuous random variable. Then, the rest of the unit will focus on the normal distribution which is a specific case of continuous random variables.
