What happens to the standard score as the standard deviation increases?
The absolute value of the standard score becomes smaller.
The wisc IQ test is an example of a percentile rank a raw score a criterion-reference test or a standard score?
standard score
How do you find the mean from raw score z score and standard deviation?
To find the mean from a raw score, z-score, and standard deviation, you can use the formula: ( \text{Raw Score} = \text{Mean} + (z \times \text{Standard Deviation}) ). Rearranging this gives you the mean: ( \text{Mean} = \text{Raw Score} - (z \times \text{Standard Deviation}) ). Simply substitute the values of the raw score, z-score, and standard deviation into this formula to calculate the mean.
A raw score of 6 has a z score of what?
A z-score requires the mean and standard deviation (or standard error). There is, therefore, not enough information to answer the question.
If a test score of 83 was transformed into a standard score of -1.5 and the standard deviation of the scores was 4 what is the mean?
78
What happens to the standard score as the standard deviation increases?

What happens to the standard score as the standard deviation increase?
The standardised score decreases.

What tells how many standard deviations a measurement is away from the mean?
the Z score, or standard score.

What does denominator of z-score measure?
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
If a test score of 83 was transformed into a standard score of -1.5 and the standard deviation of the scores was 4 what is the mean?
78
Which is better a score of 92 on a test with a mean of 71 and a standard deviation of 15 or a score of 688 on a test with a mean of 493 and a standard deviation of 150?
score of 92
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 is Hypothesis Testing of Test Statistic?
The standard score associated with a given level of significance.
Billy scores 5 What is his standard score?
3.5-5=-1.5 -1.5/.5=-3 Billy's standard score is 3
