Is the variance of a group of scores the same as the squared standard deviation?
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
What is the square of the standard deviation called?
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.
What is the relationship between standard deviation and variance for the same sample data?
The standard deviation is the square root of the variance.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.

Can standard deviation be larger then its variance?
No. The standard deviation is the square root of the variance.

How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.
Can the Variance ever be smaller than standard deviation?
Yes. If the variance is less than 1, the standard deviation will be greater that the variance. For example, if the variance is 0.5, the standard deviation is sqrt(0.5) or 0.707.
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
Is the variance of a group of scores the same as the squared standard deviation?
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
Is variance the square root of standard deviation?
No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.
Standard deviation is 13.1 What is the variance?
Standard deviation, σ = 13.1 Variance, σ2 = 171.6
Is variance directly proportional to standard deviation?
Variance isn't directly proportional to standard deviation.
Can standard deviation and variance be negative?
No. Neither the standard deviation nor the variance can ever be negative.
