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
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
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 happens to the standard score as the standard deviation increases?
The absolute value of the standard score becomes smaller.
What happens to the standard score as the standard deviation increase?
The standardised score decreases.
The wisc IQ test is an example of a percentile rank a raw score a criterion-reference test or a standard score?
standard score
What tells how many standard deviations a measurement is away from the mean?
the Z score, or standard score.
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.
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
What statistic is produced when the difference between a score and then mean is divided by the standard deviation?
z-score or standard score... tells you how many standard deviations away from the mean a particular number is in relations to all numbers in a population (or sample)
