How do i find square root of a variance

Discrete variables

Calculate the mean.

Subtract the mean from each observation.

Square each of the resulting observations.

Add these squared results together.

Divide this total by the number of observations (variance, S2).

Use the positive square root (standard deviation, S).

Your answer is:

Find the mean of the data set. Add all data values and divide by the sample size n. Find the squared difference from the mean for each data value. Subtract the mean from each data value and square the result. Find the sum of all the squared differences.

Hope it helps.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
