The formula for the normal distribution is: f(x) = 1 √2πσ2e − (x − μ)2 2σ2, However, what are e and π doing there? π is about circles and the ratio to its diameter, for example. e is mostly about exponential functions, specifically about the fact that d dxex = ex.
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”).
28 Φεβ 2018 · ISLR (An Introduction to Statistical Learning) states: Let $π_k$ represent the overall or prior probability that a randomly chosen observation comes from the kth class. This above is in reference to the the Bayes Theorem.
There are standard notations for the upper critical values of some commonly used distributions in statistics: or () for the standard normal distribution, or (,) for the t-distribution with degrees of freedom

6 Δεκ 2021 · Understand how bell curves are formed and their counterintuitive relationship to the number Pi. While recently looking through an old stats textbook, I came across the familiar equation for the normal distribution: Anyone that’s taken a statistics course in university has come across this equation.
