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 do you calculate raw score if z-score is given?

Without more information you cannot.


How do you calculate a raw score from a z score?

z = (x - μ) / σ is the formula where x is the raw score and z is the z-score. μ and σ are the mean and standard deviations and must be known numbers. Multiply both sides by σ zσ = x-μ Add μ to both sides μ + zσ = x x = μ + zσ You calculate the raw score x , given the z-score, μ and σ by using the above formula.


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


What is the z-score for 45.00?

There is insufficient information in the question to properly answer it. In order to compute a Z score from a raw score, you need the mean and the the standard deviation, neither of which was given. Please restate the question.


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.


Does a positive raw score always result in a positive z score?

No.
