WebThe variance of a random variable tells us something about the spread of the possible values of the variable. For a discrete random variable X, the variance of X is written as Var (X). Var (X) = E [ (X – m) 2 ] where m is the expected value E (X) This can also be written as: Var (X) = E (X 2) – m 2. The standard deviation of X is the square ... WebThe general formula for the normal distribution is. f ( x) = 1 σ 2 π ⋅ e ( x − μ) 2 − 2 σ 2. where. σ (“sigma”) is a population standard deviation; μ (“mu”) is a population mean; x is a value or test statistic; e is a mathematical constant of roughly 2.72; π (“pi”) is a mathematical constant of roughly 3.14. irc covid testing
