When a student takes a test or examination the result they receive, as a number, is often called a score. The average of a collection of scores, say for one class of students, is called a mean score. Mean is just another word for average.

How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
What is a z-score?
z score is defined as z = (x-mean)/sd, where mean is the mean of the sample (or population) and sd is the standard deviation of the sample or the population. x is the raw score. z-score standardizes the data. The standardized data will have a zero mean and unit variance. It has numerous applications in statistics.
What is true if someone has a z score of zero?
Z score of 0 is the mean of the distribution.
How do you find out the z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
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.
Your MELD score is 18 what does that mean?
my meld score is 16. what does that mean?
What does a positive Z-score mean?
it means that the score is above the mean
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.
Calculate the z-score for a test score of 87 if the mean test score is 81.1 and standrd deviation is 11.06?
z score = (test score - mean score)/SD z score = (87-81.1)/11.06z score = 5.9/11.06z score = .533You can use a z-score chart to calculate the probability from there.
What does score mean in maths EG three score minus sixteen?

What does four score. Mean?
a score is equal to twenty, so four score is 80
What does four score mean?
a score is equal to twenty, so four score is 80
What does the z score of - 1.3 mean?
A z score of -1.3 means that the score is located at the negative 1.3 sigma level with respect to the mean.
What does ' score a brace' mean?
