WebbThe equation for determining the standard deviation of a series of data is as follows: i.e, σ=√v. Also, µ =∑x/n. Here, σ is the symbol that denotes standard deviation. n is the number of observations in a data set. x i is the i th number of observations in the data set. µ is the mean of the sample. V is the variance. WebbThese numerical values "68%, 95%, 99.7%" come from the cumulative distribution function of the normal distribution..
