RANDOM WALK Meaning and
Definition
-
A random walk is a statistical concept that refers to a mathematical behavior or process where future steps or movements are completely unpredictable or selected at random, without any correlation or influence from previous steps or movements. In this context, "random" denotes a lack of predetermination or patterns, as well as an absence of external factors influencing the direction or nature of the walk.
The concept of a random walk can be observed in various fields, such as mathematics, physics, finance, and computer science. In mathematics, a random walk often refers to the movement of a point or particle in a series of steps, each of which is taken in a random direction or distance. In physics, random walks have been extensively studied to model the movement of molecules or particles in a fluid or gaseous environment.
In finance, a random walk is commonly used to describe the behavior of stock prices and other financial variables. The random walk hypothesis suggests that stock price movements are purely random and cannot be predicted based on past price trends or historical data. This hypothesis is an essential building block for many financial models and investment strategies.
In computer science, random walks can be utilized in various algorithms or simulations to model complex systems or perform tasks like generating random numbers. The randomness of a walk makes it suitable for exploring unfamiliar or unknown spaces, as well as simulating natural or unpredictable phenomena.
Overall, a random walk refers to a statistical process or behavior characterized by unpredictable and independent movements or steps, without any influence from past occurrences.

Etymology of RANDOM WALK
The term "random walk" is derived from the words "random" and "walk".
The word "random" comes from the Old French word "randir", which means "to run or jump". Over time, it evolved to mean "impetuosity" or "unpredictability". Eventually, "random" came to refer to something that lacks a discernible pattern or follows no specific rules.
The word "walk" comes from the Old English word "wealcan", which means "to roll" or "to move". It developed to represent the action of moving by placing one foot in front of the other.
When combined, "random walk" signifies a process or mathematical model in which the steps or movements taken are random or unpredictable. This term is significant in fields such as mathematics, physics, and finance, where it describes a mathematical model or stochastic process characterized by random steps or movements.
