A "sample," on the other hand, is only a part of that group. These symbols have the same meaning; commonly × is used to mean multiplication when handwritten or used on a calculator 2 × 2, for example. $ X $ - set of population elements. In statistical computations it is desirable to have a simplified system of notation to avoid complicated formulas describing mathematical operations. 8 years ago. The union of two sets is represented by ∪. The dissemination of important knowl-edge needs to be conveyed in ways that all consumers can understand (a main rationale for this glossary). Because "x" is a random variable, x-bar is not the same number if it is measured repeatedly. Answer Save.
