StdDevPopulation

Returns the population standard deviation of an array, dividing by n.

Syntax

StdDevPopulation( byref a as Array( of T ) ) as float64

Notes

• The n divisor, for when the array is the whole population.
• StdDev is the n-1 form and the usual choice for measured data.

Examples

#import "std/numeric"
#import "std/containers"
using numeric
using containers

dim as Array( of float64 ) a = { 2.0, 4.0, 4.0, 4.0, 6.0 }

print StdDevPopulation( a )   '' 1.264911064067352
print StdDevPopulation( a ) < StdDev( a )       '' -1 (true)
