Are standardized scores and z-scores the same thing?
Consider the following distribution of scores with a mean of 90 and a standard deviation of 30. For the letters A, B, C, and D in the boxes beneath the line labeled “z” give the z-scores corresponding to each position in the distribution. One z-score is already filled in (–1).
Suppose you also want to standardize these scores to a “k” scale where the mean of k is 100 and the standard deviation is 15. For the letters E, F, G, and H in the boxes beneath the line labeled “k” give the k-scores corresponding to each position in the distribution. One k-score is already filled in (115).

A distribution with µ = 55 and σ = 6 is being standardized so that the new mean and standard deviation will be µ = 50 and σ = 10. When the distribution is standardized, what value will be obtained for a score of X = 58 from the original distribution? a.58 b.55 c.61 d.53 On an exam with μ = 52, you have a score of X = 56. Which value for the standard deviation would give you the...

What proportion of a normal distribution is located between each of the following Z-score boundaries? a. z= -0.50 and z= +0.50 b. z=-0.90 and z= +0.90 c. z=-1.50 and z= 1.50 For a normal distribution with a mean of μ = 80 and a standard deviation of σ= 20, find the proportion of the population corresponding to each of the following. a. Scores greater than 85. b. Scores less than 100. c. Scores between 70 and 90. IQ test scores are standardized to produce a normal distribution with...

Proportions (percentages) in a Z Distribution A large population of scores from a standardized test are normally distributed with a population mean (μ) of 50 and a standard deviation (σ) of 5. Because the scores are normally distributed, the whole population can be converted into a Z distribution. Because the Z distribution has symmetrical bell shape with known properties, it’s possible to mathematically figure out the percentage of scores within any specified area in the distribution. The Z table provides...

A state administered standardized reading exam is given to eighth grade students. The scores on this exam for all students statewide have a normal distribution with a mean of 532 and a standard deviation of 48. A local Junior High principal has decided to give an award to any student who scores in the top 10% of statewide scores. How high should a student score be to win this award? Give your answer to the nearest integer.
