Description: Motion graphic web presentation examining the elemental one dimensional random walk showing how its probability distributions develop. Format allows independent accessibility of animated images and text.

Random Walk tutorial, random walk definition, meaning, random walk example, statistics, statistical mechanics, physics, mathematics , in their simplest incarnation, refer to this situation: The proverbial drunk is clinging to the lamppost. He decides to start walking. The road runs east and west. In his inebriated state he is as likely to take a step east (forward) as west (backward). (Probability 50% in either of the two directions.) From each new position he is again as likely to go forward as backward. Each of his steps are of the same length but of random direction - east or west. In the figure the drunk is a green rectangle which steps (bounces) either left or right, at random, starting at the lamppost in the center. Mouse-click on the start/stop button to begin a random walk. The same button resets the walker for another - different - random walk.
