The effects of three different types of transformations of raw scores are investigated including developmental standard scores, grade equivalents, and percentile ranks. All the procedures discussed appear viable. A general recommendation is made that test users select a procedure based on various factors...
Given mean = 50, standard deviation = 5, determine the following: a) Raw - 30, what are the z-scores, T-scores, and approximate percentile ranks? b) Raw - 65, what are the z-scores, T-scores, and approximate percentile ranks? A. Find z such that 7...
Given mean = 50, standard deviation = 5, determine the following: a) Raw - 30, what are the z-scores, T-scores, and approximate percentile ranks? b) Raw - 65, what are the z-scores, T-scores, and approximate percentile ranks? The mean of...
b) Raw - 65, what are the z-scores, T-scores, and approximate percentile ranks? If the probability of getting a z-score between the mean and +1 standard deviation is 0.3413, what is the probability of getting a z-score of +1 standard deviation or less?...
For any distribution, what is the z-score corresponding to the mean? Given mean = 50, standard deviation = 5, determine the following: a) Raw - 30, what are the z-scores, T-scores, and approximate percentile ranks? b) Raw - 65, what are the z-scores, ...
Given mean = 50, standard deviation = 5, determine the following: a) Raw - 30, what are the z-scores, T-scores, and approximate percentile ranks? b) Raw - 65, what are the z-scores, T-scores, and approximate percentil...
