A negative Z-Score corresponds to a negative standard deviation, i.e. an observation that is less than the mean, when the standard deviation is normalized so that the standard deviation is zero when the mean is zero.

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

Does a negative z score yield a negative probability value?

no, z score can be negative but a probability is a always positive between 0 and 1.

How do you interpret a negative z- score?

A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.

How do you find probabilty of negative z score?

Let z be positive so that -z is the negative z score for which you want the probability. Pr(Z < -z) = Pr(Z > z) = 1 - Pr(Z < z).

What is measured by the sign of a z-score?

The sign of the z score is negative if the observation was below the mean and positive if it was greater.

How do you change a negative z score to a decimal?

In the same way that you would convert a positive z-score. Only leave a negative sign in front of it.

Can a negative z score be greater than a positive z score?

Assume the z-score is relative to zero score. In simple terms, assume that we have 0 < z < z0, where z0 is the arbitrary value. Then, a negative z-score can be greater than a positive z-score (yes). How? Determine the probability of P(-2 < z < 0) and P(0 < z < 1). Then, by checking the z-value table, you should get: P(-2 < z < 0) ≈ 0.47725 P(0 < z < 1) ≈ 0.341345

Does anyone know any positive and negative character traits that start with the letter z and that start with the letter k too?

Positive Z: zealous, zestful. Negative Z: ??? Positive K: Kind, keen Negative K: kooky(?)

What is the meaning of a negative z score?

A negative z score is a value that is less than the mean value.

Does a positive raw score always result in a positive z score?


Why does a negative z score produce positive results?

well why can't pigs fly? same thing!

Is a negative z score always an indicator that the raw score is below the mean?

Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.

What does a negative z-score mean?

z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
