Sagot :

Data:

variance: 4.4

The standar deviation is defined in relation to the variance as the square root of the variance, so:

[tex]\sigma=\sqrt[]{\sigma^2}[/tex]

Where:

σ is standar deviation

σ^2 is the variance

So in this case the standar deviation will be:

[tex]\sigma=\sqrt[]{4.4}[/tex][tex]\sigma=2.2097[/tex]
