If the variance is 846, then the standard deviation is 29.1, the square root of 846.
No. The standard deviation is the square root of the variance.
Square the standard deviation and you will have the variance.
is variance the square of the standard deviation
Standard deviation = square root of variance.
Standard deviation is the square root of the variance.
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
Variance isn't directly proportional to standard deviation.
Standard deviation, σ = 13.1 Variance, σ2 = 171.6
No. Neither the standard deviation nor the variance can ever be negative.
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.
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.
Standard deviation = square root of variance.
