Introduction to Statistical Methods
We have chosen the problem of the random walk in one dimension to introduce some concepts and techniques of the theory of probabilities. We use this problem to analyze the main features of binomial and Gaussian distributions, to define mean (expected) values and standard deviations, and to investigate the role of large numbers. The simplest versions of the random walk problem are already related to models of physical interest, suggested by the diffusion of particles in a viscous medium.
