Yes.

z = (raw score - mean)/standard error.

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

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

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.

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

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

An IQ score of 97 is just below average.

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.

Yes. If a score is below the mean, the z score will be negative.

A percentile is always between 0% and 100%, never negative.

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

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.

as long as your credit file contains negative information it will always impact your credit score

A lexile score for students in fifth grade is 800 so I guess any score above that is good. If you are below, you can always catch up!

Credit score that is around or more than 700 is considered to be good and score below 500 is considered to be bad. It is always advised to constantly monitor your credit score.

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