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. |
Syntax
double StdDevP(dataset vd)
double StDev.p(dataset vd)
Parameters
vd
- Input dataset.
Return
Return the Population Standard Deviation.
Example
EX1
double ee=StdDevP(col(A)); ee=;
EX2
range rr=1!1[1]:2[10]; StDev.p(rr)=;
