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.
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.
For z-score calculation, mean and std deviation must be given.
There is insufficient information in the question to answer it. To determine Z score, you need raw score, mean, and standard deviation. Please restate the question.
This question cannot be answered. You need the mean and standard deviation in order to compute a Z score for a Raw score. Please restate the question.
You need the mean and standard deviation in order to calculate the z-score. Neither are given.
Without more information you cannot.
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.
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
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.
Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.
No.
There is not enough information to answer your question. To determine a Z-Score, the mean and standard deviation are also required.

A z-score requires the mean and standard deviation (or standard error). There is, therefore, not enough information to answer the question.
