What else can I help you with?
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
Is it true or false that the standard deviation of a set is always smaller than the variance of that set?
False. The standard deviation of a set is the square root of the variance, so it is not always smaller; in fact, it is always less than or equal to the variance when the variance is positive. The standard deviation can be equal to the variance only when the variance is 1 (since the square root of 1 is 1).
How do you convert variance of 10.8 square inches into standard deviation?
Standard deviation = square root of variance.
What is the standard deviation of a variance of 846?
If the variance is 846, then the standard deviation is 29.1, the square root of 846.
Can standard deviation be larger then its variance?
No. 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.
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
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.
Is it true or false that the standard deviation of a set is always smaller than the variance of that set?
False. The standard deviation of a set is the square root of the variance, so it is not always smaller; in fact, it is always less than or equal to the variance when the variance is positive. The standard deviation can be equal to the variance only when the variance is 1 (since the square root of 1 is 1).
What is the standard deviation of a variance of 846?
If the variance is 846, then the standard deviation is 29.1, the square root of 846.
How do you convert variance of 10.8 square inches into standard deviation?
Standard deviation = square root of variance.
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.
Why standard deviation is better measure of variance?
1. Standard deviation is not a measure of variance: it is the square root of the variance.2. The answer depends on better than WHAT!
What is the square root of the variance called?
Standard deviation
What is the relationship between standard deviation and variance for the same sample data?
The standard deviation is the square root of the variance.
