A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


Can standard deviation be larger then its variance?

No. The standard deviation is the square root of the variance.


How do you convert variance of 10.8 square inches into standard deviation?

Standard deviation = square root of variance.


How do you calculate standard deviation if I know variance?

Standard deviation = square root of variance.


The difference between variance and standard deviation?

The SD is the (positive) square root of the variance.


What is the relationship between standard deviation and variance?

Standard deviation is the square root of the 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 standard deviation the positive square root of the variance?

Yes.


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.


What is the standard normal deviation?

The standard deviation of a normal deviation is the square root of the mean, also 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.


How do you work out variance?

you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
