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.
Is it true any score with value less than the population mean will have a negative z-score?
Yes. If a score is below the mean, the z score will be negative.
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.
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.
A negative z score always indicates that the raw score is below the mean?
Vale verga ;)
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 many point does credit score increase with each negative item removed?
There is no formula for a credit score. Once you do have the negative items removed the scores will start to improve, but no one can tell you by how much.
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.
In foil fencing what is the target area you need to hit to score a point?
The are you need to hit to score a point is the torso and a little wedge below your waist on the front (where the silver-colored lamé is).
What does a z score of -4 indicate?
It means that your raw score is four standard deviations below the mean. This will mean different things depending on the context of the question. If you're looking at the probability of a single score occurring in a given distribution (say, a score of 40 in a distribution of scores with a mean of 80 and a std. dev. of 10), then this means that the probability of getting a 40 is very, very low--less than .00002.
What is the probability of obtaining a score from a distribution that would have a z score of -1.55 or smaller?
It is 0.0606
