| 520 | |a The simplicity of standard score systems, percentile equivalents, and their relation to the ideal normal distribution are discussed and illustrated. Standard scores are z-scores, the T-scores, College Entrance Examination Board scores, and Army General Classification Test scores. A derivative of the general standard score system is the stanine plan, which divides the norm population into nine groups and nine percentages which indicates the percent of the total population in each of the stanines. Interpretation of the Wechsler scales depends on a knowledge of standard scores. A subject's raw score on each of the subtests in these scales is converted, by appropriate norm tables, to a standard score, based on a mean of 10 and a standard deviation of 3. The sums of standard scores on the Verbal Scale, the Performance Scale, and the Full Scale are then converted into IQ's. These IQ's based on a standard score mean of 100; the standard deviatn of the IQ's set at 15 points. IQ's of the type used in the Wechsler scales are known as "deviation IQ's" as contrasted with the IQ's developed from scales in which a derived mental age is divided by chronological age.
