Definition: Let $X$ be a random variable or a set of random variables. Then, a sample, also “statistical sample”, is a set of realizations of this random variable, obtained via observation and measurement within random experiments:
\[\label{eq:samp} x = \left\lbrace x_1, \ldots, x_n \right\rbrace \; .\]- Elliott, Graham (2024): "Sampling"; in: Understanding Statistics, retrieved on 2024-11-15; URL: https://econweb.ucsd.edu/~gelliott/Chapter5.html.
