Statistics use distinct symbols to represent specific information. Parameters are usually represented by

In statistics, parameters are typically represented by lowercase Greek letters. This convention is heavily utilized because Greek letters provide a clear distinction from other symbols representing different types of statistics, such as sample statistics. For example, the population mean is often denoted by the Greek letter mu (μ), while variance might be represented by sigma squared (σ²). This use of Greek letters helps to streamline notation and reduce confusion when discussing various statistical measures.

Other symbol representations, such as lowercase English letters, lowercase Roman numerals, and lowercase Roman letters, are generally reserved for different contexts within statistics. Lowercase English letters often denote individual sample values, while lowercase Roman letters can represent specific quantities or data points. The use of lowercase Roman numerals is rare and typically pertains to specific parts of a problem rather than statistical parameters. Thus, lowercase Greek letters are the standard symbols for representing parameters in statistical notation.
