Discover common statistical symbols: Learn the meanings and uses of symbols often used in statistics for data analysis.
Central Tendency: The Mean Vector. Throughout this course, we’ll use the ordinary notations for the mean of a variable. That is, the symbol μ is used to represent a (theoretical) population mean and the symbol x ¯ is used to represent a sample mean computed from observed data.
μ (mu) is a symbol commonly used to represent the population mean in statistics, which is the average value of a set of observations in a given population. This key concept serves as a foundation for understanding statistical inference, as it helps in estimating and drawing conclusions about larger groups based on sample data.
