WebThe formulas to calculate the standard deviations of population and sample differ a little. The population standard deviation formula is given as: σ = √ 1 N ∑N i=1(Xi −μ)2 σ = 1 N ∑ i = 1 N ( X i − μ) 2. Here, σ = Population standard deviation symbol. μ = Population mean. N = total number of observations. WebDefinition of Deviation. Deviation is a statistical concept that refers to the difference between an observed value and the expected value. In other words, deviation is the amount by which a data point or measurement differs from the average or expected value.
