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. WebThe standard deviation measures the degree of dispersion of a collection of data. Each data point is compared to the average of all the data points, and the standard deviation gives a determined number that indicates whether the data points are clustered together or dispersed. The standard deviation of a normal distribution indicates how far ...

In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean. The sign of the deviation reports the direction of that difference (the deviation is positive when the observed value exceeds the reference value). The magnitude of the value indicates the size of the difference. Webdeviate meaning: 1. to do something that is different from the usual or common way of behaving: 2. to go in a…. Learn more.
