Exam 5: Z Scores, T Scores and Other Normal Curve Transformations

With a mean of 100 and an SD of 20, what raw score would fall at the 75th percentile?

The range of the T score distribution is approximately 10.

When a raw score translates into a negative z score, the resulting percentile must be

A percentile rank of 45 indicates that

When T=50, then z=0.

On the T score distribution the standard deviation always equals 10.

The mean is 38.70 with an SD of 6.31. What score falls at the 11th percentile?

A person with a T score of greater than 50, must have a negative z score.

Whenever the value of the standard deviation is positive, then

For the questions below ,find the T score. -z = 1.28

The mean equals 100. One individual scores at the 58th percentile and has a raw score of 107. What is the standard deviation?

For the questions below ,find the T score. -z = 0 68

Raw scores may never be converted into T scores unless the raw score distribution is normal.

With an SD of 35, a raw score of 145 is at the 53^rd percentile, Find the mean of the raw score distribution.

When converting percentiles into z scores, it is essential to know

All T scores are positive in sign.

With a mean of 100 and an SD of 20, what raw score would fall at the 27th percentile?

If the mean of the raw score distribution equals 68 with a standard deviation of 3, then a person with a raw score of 65 would have a T score of

A z score of +3.00, means that

The T score on a certain distribution is 28. The mean of the raw score distribution is 110 with an SD of 14.93. What is the value of the raw score?
