The variance of a given distribution is 25. What is the standard deviation?
Answer Details
The standard deviation is the square root of the variance. Therefore, to find the standard deviation when given the variance, we simply take the square root of the variance.
In this case, the variance is given as 25. Taking the square root of 25 gives us:
sqrt(25) = 5
So the standard deviation of the distribution is 5.
To summarize, the formula for finding the standard deviation from the variance is to take the square root of the variance. In this case, the variance is 25, so the standard deviation is 5.
