Notational Symbols. Notational symbols are often conventions or acronyms that don’t fall into the categories of constants, variables, operators and relational symbols. The following table documents some of the most common notational symbols in probability and statistics — along with their respective usage and meaning.

Probability and Statistics Symbols. I’ve put these statistics symbols into quasi-alphabetical order, so that they are easy to find. When I say quasi-alphabetical, I mean that I have ordered them according to what they look like. For example, the Greek letter Beta (β) looks like the letter b, so you’ll find it in the b section. Same for the ...

Statistics is the language of research. Students need to master these symbols because these symbols are the standard nomenclature in statistical reasoning. In general, Greek letters are used for measures of the population (called “parameters”) and Latin letters are used for measures of one or more samples (called “statistics”). The
Probability and statistics are separate but two related academic disciplines. Statistical analysis often uses probability distributions, and the two topics are often studied together.

Symbols: Summation Notation; Statistics (and mathematics) uses symbols to make things easier and clearer. Symbols help express complex ideas quickly and efficiently, allowing us to communicate universally without language barriers. They ensure precision and avoid ambiguity, making understanding and working with mathematical concepts easier.

You will see that in other statistics sources, it is common to put a hat on the population parameter when referring to its estimate (e.g. , , , etc.). We have usually not done this in order to keep the notation simple. Some symbols are so universal that we have retained them, most notably as the estimate of the population mean μ. Critical values
