Deviation (statistics) - Wikipedia

WebThis does not give us any idea about measure of variability of the data which is the actual purpose of finding the mean deviation. So, we find the absolute value of deviation from the mean. In the above example the … 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.
