Question

For the standard deviation how do you transfer 10,074 to 100.37 For the sample variance how do you make 10,074 to 10,074

Answer 1

We have a calculation of the sample standard deviation and the sample variance.

The standard deviation is calculated with the following formula:

`\sigma=(1)/(n-1)\sum ^n_(i=1)(x_i-M)^2`

M: sample mean.

The standard deviation in this case has he value:

`\sigma=\sqrt[]{(30,222)/(3)=\sqrt[]{10,074}\approx100.37}`

Key to calculate the square root.
