If you would like to read more about the alpha symbol and its many meanings, check out our detailed article below: Betaīeta (βήτα) is the second letter in the Greek alphabet. It also has a powerful religious meaning within the context it was used in the Bible verses when God made the statement “I am the Alpha and Omega” as in “I am the beginning and the end of everything”. Alpha is written as A in uppercase and α in lowercase.Īlpha symbol is used to denote many things including absorption factor, area, angles and coefficients P = 0.Alpha ( άλφα ) is the first letter of the Greek alphabet. Probability or p-value in hypothesis testing Here's a table summarizing these symbols: Symbol ![]() The population mean is the average of all the values in a population.Įxample: If μ = 10, it means the average value of all the data in the population is 10. Mu (μ) is the Greek letter used to represent the population mean in statistics. Standard deviation is a measure of the amount of variation or dispersion in a set of values.Įxample: If σ = 3, it means the values in the data set are spread out by 3 units from the mean on average. Sigma (σ) is the Greek letter used to represent the standard deviation in statistics. It can also represent a p-value in hypothesis testing, which is the probability of obtaining a result as extreme as the observed data, assuming the null hypothesis is true.Įxample: If p = 0.05, it means there is a 5% chance of the event occurring. The symbol "p" is often used to denote the probability of an event. In statistics and mathematics, the symbols p, σ (sigma), and μ (mu) are commonly used to represent specific concepts.
