Final answer:
Statistical formulas use Greek language as shorthand.
Therefore, the correct answer is: option a). Greek
Step-by-step explanation:
The Greek language has provided symbols that are internationally recognized in the realm of mathematics and statistics for various constants, variables, functions, and to represent certain values.
Examples of Greek letters used in statistics include Alpha (A, α), Beta (B, β), Gamma (Γ, γ), and many others as shown in Table C5 of the Greek Alphabet.
These symbols are used to denote parameters, variables, and specific concepts in statistical equations and theorems.
A variable represents a model state, and may change during simulation. A parameter is commonly used to describe objects statically.
A parameter is normally a constant in a single simulation, and is changed only when you need to adjust your model behavior.
The most common convention in statistics is to use Greek letters for parameters (μ,σ for normal distributions, λ for Poisson, β when parameterizing the mean in regression and GLMS, etc).
