Measures are methods or techniques for describing and assessing attributes of objects that are of concern to us. True False 2. When developing measures, it is a good idea to give each rater some license to interpret the meaning of scores as fits the specific situation. True False 3. To achieve standardization the content of job application tests should be the same for all applicants. True False 4. Scoring keys for tests should be developed immediately after the test has been administered. True False 5. Most staffing measures can be best described as being on a ratio scale. True False 6. A rank ordering of five job candidates in terms of overall qualification for the job is an example of an ordinal scale. True False

7. Research shows that when an attribute is measured by both objective and subjective means, there is often relatively low agreement between scores from the two types of measures. True False 8. The standard deviation is a measure of the central tendency of a scale. True False 9. The most appropriate measure of central tendency for nominal scale data is the median. True False

10. Standard scores are also useful for determining how a person performed, in a relative sense, on two or more tests. This is helpful for comparing relative standing across several tests. True False 11. If an individual has a z-score of 2.0 on a performance test, this indicates this person's score is twice as high as the average test score. True False 12. A correlation coefficient ranges from 0 to +1. True False 13. A correlation between two variables does not necessarily that one causes the other. True False 14. A standard level for statistical significance is p<.50. True False

15. With very large samples, it is possible for a fairly weak relationship to still be statistically significant. True False 16. Measurement standardization applies to measurement content, not the administration of measurements. True False 17. When numbers are assigned by category, this reflects an ordinal scale of measurement. True False 18. If scores are classified as "low", "medium", and high", the scale of measurement is nominal. True False 19. Human body weight is an example of a variable measured on a ratio scale of measure. True False 20. Numerical employment interview ratings represent objective measures. True False 21. Performance appraisal ratings are subjective measures. True False

22. The research literature indicates a high correlation between subjective and objective measures of performance. True False

23. A correlation score of minus one between two sets of scores indicates an exceptionally low association or relationship between the two sets. True False 24. If the correlation coefficient between variables X and Y is .90, this means that the proportion of common variance shared by the two variables is ninety percent. True False 25. A correlation coefficient of 1.0 between variables X and Y indicates that there is a perfect linear relationship between these two variables. True False 26. The correlation coefficient does not measure the change in one variable caused by another variable. True False 27. While correlation is valuable as an indicator of the degree of association between variables, it is generally not used as a tool for prediction. True False

A. rank order B. an absolute true zero point C. classification by categories D. equal differences between points on a scale of measurement 32. A scale in which objects are rank ordered according to how much of the attribute they possess. A. nominal B. ordinal C. interval D. ratio 33. A scale in which objects are rank ordered according to how much of the attribute they possess, with equal space between objects. A. nominal B. ordinal C. interval D. ratio

34. A scale in which a given attribute is categorized, and numbers are assigned to the categories, but there is no order or level implied among the categories. A. nominal B. ordinal C. interval D. ratio 35. Rankings of the finishes of competitors in a foot race is an example of a(n) _______. A. ratio scale B. ordinal scale C. interval scale D. none of the above 36. Length in inches is an example of a(n) _________. A. ratio scale B. nominal scale C. ordinal scale D. interval scale

37. The most appropriate measure of central tendency for nominal data is the ______. A. mean B. median C. standard deviation D. mode 38. The variability of a measure is best captured by the _____________. A. mean and standard deviation B. range and standard deviation C. range and median D. mode and mean

39. The likelihood that a correlation exists in a population, based on knowledge of the actual value of r in a sample from that population is the ____________. A. practical significance B. likelihood ratio C. functional statistic D. statistical significance 40.
