If a score s equal to the mean it and z score will be?
If a score ( s ) is equal to the mean of a dataset, its z-score will be 0. The z-score is calculated using the formula ( z = \frac{s - \mu}{\sigma} ), where ( \mu ) is the mean and ( \sigma ) is the standard deviation. Since ( s ) equals ( \mu ), the numerator becomes zero, resulting in a z-score of 0. This indicates that the score is exactly at the average of the dataset.
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 positive Z-score mean?
it means that the score is above the mean
What is the Z score equation?
Given a random variable X with mean M and standard deviation S, Z = (X - M)/S
How can you calculate z-score?
If a normally distributed random variable X has mean m and standard deviation s, then z = (X - m)/s
If a score s equal to the mean it and z score will be?

Since ( s ) equals ( \mu ), the numerator becomes zero, resulting in a z-score of 0. This indicates that the score is exactly at the average of the dataset.
What is the z score for a given raw score?
Let your raw score be x and M the mean and S the standard deviation. The Z score for your specific x is Z=(x-M)/S So say your score is 80 (out of 100) and the mean is 70 and the standard deviation is 10. Then the z score for your 80 is: (80-70)/10=1 If on the other hand you got a 60, then the z score would be -1.
How z-score derive?
If a random variable X has a normal distribution with mean m and standard error s, then the z-score corresponding to the value X = x is (x - m)/s.
What does it mean if the Z score of a test is equal to 0?
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
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 positive Z-score mean?
it means that the score is above the mean

What does it mean if s an an eleven year old girl gets an IQ score of 132?
She's a genious
What is the Z score equation?
Given a random variable X with mean M and standard deviation S, Z = (X - M)/S
What does s mean in baseball stats?
Strike In the box score an "s" denotes a sacrifice bunt. This results in an out for the batter, but the baserunner moves up a base.
How can you calculate z-score?
If a normally distributed random variable X has mean m and standard deviation s, then z = (X - m)/s
How do your work out z score?
If a random variable X has a Normal distribution with mean M and standard deviation S, then Z = (X - M)/S
