The conditional expected value of a continuous random variable can be calculated using itsconditional density function(see the lecture onconditional expectationfor details and examples). Common continuous distr
Random Variables can be either Discrete or Continuous:Discrete Data can only take certain values (such as 1,2,3,4,5) Continuous Data can take any value within a range (such as a person's height)In our Introduction to Random Variables (please read that first!) we look at many examples ...
In Chapter 4, we studied discrete random variables, i.e. variables whose range is countable. In this chapter, we consider variables that can take values in an interval of real numbers. Such variables are calledcontinuous.Examples of continuous random variables are: the length, the area, the ...
Continuous random variables Expectation and variance of continuous random variables Measurable sets and a famous paradox Examples � Suppose that f X (x) = 1/2 x ∈ [0, 2] . 0 x �∈ [0, 2]. � What is Var[X ]? � Suppose instead that f X (x) = ...
In this blog post, you’ll learn about their properties and see examples of both discrete and continuous random variables. Discrete Random Variable A discrete random variable has distinct values that are countable and finite or countably infinite. This data type often occurs when you are counting...
We have in fact already seen examples of continuous random variables before, e.g.,Example 1.14. Let us look at the same example with just a little bit different wording. Example I choose a real number uniformly at random in the interval[a,b][a,b], and call itXX. By uniformly at ran...

Example: Uniform Distribution A continuous random variable has a uniform distribution if its values are spread evenly over a certain range. Example: voltage output of an electric generator is between 123 V and 125 V. The actual voltage level may be anywhere in this range. 4...
