What happens to the standard score as the standard deviation increases?

The absolute value of the standard score becomes smaller.

If each score in a set of scores were increased by 6 points how would this affect the mean and the standard deviation?

This would increase the mean by 6 points but would not change the standard deviation.

Why use the T score?

T-score is used when you don't have the population standard deviation and must use the sample standard deviation as a substitute.

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

How do you calculate standard deviation with the help of z-score?

A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.

standard deviation

When is a t test better than a z score?

Can The standard deviation of a distribution be a negative value?

No. The standard deviation is not exactly a value but rather how far a score deviates from the mean.

How are Stanford-Binet intelligence scale results measured?

.The test has a mean, or average, standard score of 100 and a standard deviation of 16 (subtests have a mean of 50 and a standard deviation of 8). The standard deviation indicates how far above or below the norm the subject's score is.

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?


What does denominator of z-score measure?

The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
