A review of five interrelated studies showed that certain preselected SVIB occupational scales were indicative of life styles related to accident incurrence. The hypothetical formulation underlying these studies was that vocational interest scores reflect enduring personal characteristics. (Author)

THE NINE APTITUDES MEASURED BY THE GENERAL APTITUDE TEST BATTERY ARE INTELLIGENCE, VERBAL APTITUDE, NUMERICAL APTITUDE, SPATIAL APTITUDE, FORM PERCEPTION, CLERICAL PERCEPTION, MOTOR COORDINATION, FINGER DEXTERITY, AND MANUAL DEXTERITY. THIS MANUAL PRESENTS (1) PERCENTILE EQUIVALENTS OF APTITUDE OR STANDARD SCORES FOR ADULTS, 10TH GRADERS, AND 9TH…

NORMS ARE SHOWN IN TERMS OF CUTTING SCORES FOR EACH OF THE APTITUDES FOUND TO BE SIGNIFICANT FOR THE OCCUPATION. THE STANDARD ERROR OF AN OBTAINED SCORE FOR EACH APTITUDE OF THE GENERAL APTITUDE TEST BATTERY IS APPROXIMATELY SEVEN POINTS. INCLUDED IN THE MANUAL ARE (1) AN ALPHABETICAL INDEX TO APTITUDE TEST BATTERIES, (2) AN INDUSTRIAL INDEX TO…

This is a report of the development of a system of scoring the Strong Vocational Interest Blank (SVIB) for Men. The scales which were developed supplement the occupational scales. Their main concern is identifying important clusters of interest which can be generalized beyond a single occupation. Development of the scales was based on an item…

Two ways of interpreting raw test data are norm-referencing and criterion-referencing; the former yields information based on some type of ordering of the person on the person's dimension, while the latter tells whether or not students can exhibit a given performance. Criterion-referenced information can be ordered into a criterion-referenced…

The toal score concept is considered from the test user's point of views. The simples kind of total, obtained by adding raw scores on the tests, automatically assigns weights to the tests which are proportional to their standard deviation. When desired or appropriate, tests can be weighted equally in a total by transforming the raw scores on each…

Results obtained by the Kudar-Richardson formula (20) adapted for use with R-KW scoring are compared with three other reliability formulas. Based on parallel tests administered at the same sitting the KR (20) estimates are compared with alternate-form correlations and with odd-even correlations adjusted by the Spearman-Brown prophecy formula.…

A correlation coefficient should not be regarded as a judgment; it is only a number summarizing the relationship of two sets of facts to each other. A coefficient's size is important, but the reason for its size is more important. A coefficient should be regarded as a clue to further investigation, which should include the test, the criterion…

GURU is a computer program developed to analyze data generated by open-ended question techniques such as ECHO or other semistructured data collection techniques in which data are categorized. The program provides extensive descriptive statistics and allows extensive flexibility in comparing data. (Author/JKS)

Confusion in the literature between the concepts of internal consistency and homogeneity has led to a misuse of coefficient alpha as an index of item homogeneity. This misuse is discussed and several indices of item homogeneity derived from the model of common factor analysis are offered as alternatives. (Author/JKS)

Some speculations regarding the response tendencies of a group of first graders are examined for ten test items. (JT)

Takahiro Sato, a Japanese engineer, has developed a method to study the composition of an objective test by finding out how individual students are responding to the test's items and by summarizing this information in a single index. The Student-Problem Chart is discussed. (MLW)

Investigated Kaufman's procedures for determining intersubtest scatter on the Wechsler Intelligence Scale for Children-Revised by means of Sattler's revised tables for determining significant subtest fluctuations. Results indicated that Sattler's revised tables yielded more conservative estimates of subtest scatter than those originally reported…
