"Variance" and "Standard deviation" are numbers that describe a set of data

that typically contains several numbers. Applied to a single number, neither

of them has any meaning.

-- The variance, standard deviation, and mean squared error of 7 are all zero.

-- The mean, median, mode, average, max, min, RMS, and absolute value of 7 are all 7 .

None of these facts tells you a thing about ' 7 ' that you didn't already know

as soon as you found out that it was ' 7 '.

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

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.
