Continuous Random Variable: Mode, Mean and Median

Statistics: Finding the Mode for a Continuous Random Variable
This tutorial shows you how to calculate the mode for a continuous random variable by looking at its probability density function.

The Formulae for the Mean E(X) and Variance Var(X) for Continuous Random Variables
In this tutorial you are shown the formulae that are used to calculate the mean, E(X) and the variance Var(X) for a continuous random variable by comparing the results for a discrete random variable. There is a brief reminder of what a discrete random variable is at the start
