what is statistically random
Check out our app! RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page describes the statistical analyses that have been conducted of the service. This question is surprisingly hard to answer. Before we try, let's define what exactly we mean by a random number. When discussing single numbers, a random number is one that is drawn from a set of possible values, each of which is equally probable. In statistics, this is called a uniform distribution, because the distribution of probabilities for each number is uniform (i.e., the same) across the range of possible values.
