WebJul 14, 2024 · The variance of a data set X is sometimes written as Var (X), but it’s more commonly denoted s 2 (the reason for this will become clearer shortly). The formula that we use to calculate the variance of a set of observations is as follows: Var ( X) = 1 N ∑ i = 1 N ( X i − X ¯) 2 Var ( X) = ∑ i = 1 N ( X i − X ¯) 2 N WebThe format of the variability profile is a generalized version of the business process variation point model introduced in our previous work [26]. Consequently, the variability …
