In statistics, which alphabet is typically used to denote population parameters?

• A. English Alphabet
• B. Greek Alphabet
• C. Cyrillic Alphabet
• D. Arabic Numerals

Answer: (B)

Population parameters are typically denoted with the Greek alphabet. This convention helps show that these values describe the entire population and are fixed but usually unknown, in contrast to sample statistics which are represented with Latin/English letters. For example, μ is used for the population mean and σ for the population standard deviation, while the sample mean is written as x̄ and the sample standard deviation as s. Digits are simply numbers, and Cyrillic letters aren’t part of the standard notation for population parameters. So the Greek alphabet is the standard way to label population parameters.
