Find Population Standard Deviation {1,2,3,2,3,6}

Solution:
Your problem `->` Population Standard Deviation {1,2,3,2,3,6}


`x``x^2`
1 1 `1=1xx1`
2 4 `4=2xx2`
3 9 `9=3xx3`
2 4 `4=2xx2`
3 9 `9=3xx3`
6 36 `36=6xx6`
------
`sum x=17``sum x^2=63`


Population Standard deviation `sigma = sqrt((sum x^2 - (sum x)^2/n)/n)`

`=sqrt((63 - (17)^2/6)/6)`

`=sqrt((63 - 48.1667)/6)`

`=sqrt(14.8333/6)`

`=sqrt(2.4722)`

`=1.5723`
