They refer to the same thing as do z-transformations.

What is the difference between Z-Test and The Z-score?
The Z-score is just the score. The Z-test uses the Z-score to compare to the critical value. That is then used to establish if the null hypothesis is refused.
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 find out the z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
What is the probability that a data value in a normal distribution is between a z-score of -1.98 and a z-score of 1.11 Round your answer to the nearest tenth of a percent?
It is 84.3%
What is the meaning of a negative z score?
A negative z score is a value that is less than the mean value.

What Z score corresponds to 17 percent of the data between the mean and the Z?
z value=0.44
What is the value of a 'z' score of 0?
A z-score of 0 means the value is the mean.
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.
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 is the z-score depicted?
z-score of a value=(that value minus the mean)/(standard deviation)
What is meant by a z-score?
z-score of a value=(that value minus the mean)/(standard deviation)

What is the meaning of a negative z score?
A negative z score is a value that is less than the mean value.
What is the difference between the mean and z-score?
There is little in common between the two. Any set of numbers can have a mean. A z-score the standardised version of the Gaussian (or Normal) distribution. If X is a random variable that is normally distributed with mean µ and variance σ2 then Z = (X - µ)/σ is distributed with mean 0 and variance 1. Z is said to have the Standard Normal distribution. The value of Z is the z score for the random variable X..
What does a z-score of -1.5 mean?
z-score of a value=(that value minus the mean)/(standard deviation). So a z-score of -1.5 means that a value is 1.5 standard deviations below the mean.
