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.
Binomial Probability Formula. P(x) = nCxπx(1 – π)n – x, where C denotes combinations, n is the number of trials, x is the random number of successful trials, π is the probability of a success for each trial. Note: π, or pi, is not the mathematical constant of 3.14159 that you used in your geometry class to find the circumference of a circle.
18 Ιουν 2024 · Typically used for sample statistics, individual data points, and variables. Examples: \(x\) - a single data point, \(n\) - sample size, \(\bar x\) - sample standard deviation, \(\mu\) - population mean, \(\sigma\) - population standard deviation
