About this document
Understanding Discrete Random Variables by trucious is a document available to read on EtoBox.
This document defines and provides examples of random variables, expectations, and standard deviation. It introduces: - Random variables which assign values from a sample space to real numbers. - Expectation (mean) which is the average value expected from a random variable. - Standard deviation which measures how close outcomes are to the expected average. - Variance, the square of standard deviation, which is used to calculate standard deviation from expectation.
