StdDevP/StDev.p

Description

Calculate the population standard deviation.

$s = \sqrt{\frac{1}{n} \sum_{i=1}^n (x_i - \overline{x})^2}$

Notes:

StdDevP() and StDev.p() are functionally identical. Use either of them as you like.

double StdDevP(dataset vd)

double StDev.p(dataset vd)

Input dataset.

Return the Population Standard Deviation.

EX1

double ee=StdDevP(col(A));
ee=;

EX2

range rr=1!1[1]:2[10];
StDev.p(rr)=;
