Let us first define these as follows: SSQ =∑k=1n x2 k and SQS =∑k=1n xk. S S Q = ∑ k = 1 n x k 2 and S Q S = ∑ k = 1 n x k. A famous formula of the (population) 1 variance is. Var(X) = 1 n ∑k=1n x2 k −(1 n ∑k=1n xk)2 = SSQ n −(SQS n)2.Test Statistic = x ¯ - μ 0 σ n. Test Statistic = 66 - 40 4 16. Test Statistic = 26 4 4. Test Statistic = 26 1. Test Statistic = 26.

In the example shown, the formulas in F6 and F7 are: =STDEV.P(C5:C14) // F6 =STDEV.S(C5:C14) // F7Empirical Rule Formula derivation: 68% of values lies => mean ± sd. 95% of value lies => mean ± 2 sd. 99.73% of value lies => mean ± 3 sd. sd represents standard deviation for the value that is given. Mean represents the Arithmetic Mean for the given values. mean = (12+32+45+53+21+43)/6. Then find the value for Standard Deviation.The first column contains the standard deviation of all distinct values and the second column contains the standard deviation of all values including any duplicates values.
