ÿ Question 1 A z score of 3.0 for a job applicant’s score on an aptitude test indicates the applicant ______. achieved a score 3 points higher than the average score received a score 3 standard deviations above the mean score had a score 3 percent higher than the average score had a score plus or minus 3 points relative to the mean score Question 2 The most appropriate measure of central tendency for nominal data is the ______. Mean Median standard deviation mode Question 3 Content validation is most appropriate when ____________. reliability is too high sample size is large criterion measures are readily available sample size is too small for criterion validity calculation Question 4 Which of the following levels of statistical significance would provide the most confidence that a sample correlation coefficient would not be interpreted as having a relationship in the population, when, in fact, there is no such relationship? .10 .50 .01 .05 Question 5 The standard error of measurement allows ________. calculation of confidence intervals for true scores estimates of content validity calculation of confidence intervals for actual scores calculation of confidence intervals for error Question 6 A scale in which objects are rank ordered according to how much of the attribute they possess, with equal space between objects. Nominal Ordinal Interval ratio Question 7 The case for validity generalization across situations becomes stronger if ___. correlation coefficients are negative the standard error of measurement is large differences in method and statistical differences are controlled reliability is low Question 8 When predictor and criterion scores have been obtained, the predictor can be considered valid if __________. the correlation coefficient has the desired practical and statistical significance the correlation coefficient has statistical significance alone the correlation coefficient is insignificant the correlation coefficient has practical significance alone Question 9 Coefficient alpha assesses ____________. reliability within a single time period reliability between time periods reliability between samples test-retest reliability Question 10 A scale in which objects are rank ordered according to how much of the attribute they possess. Nominal Ordinal Interval ratio Question 11 The process of ensuring that all test takers receive the same tests in the same context, as a way to eliminate extraneous influences on test performance is called ____________________. Standardization Optimization Rationalization inflation Question 12 Deficiency error would not indicate a failure to _________. measure some portion of the attribute of interest adequately define the attribute of interest construct a proper measure of the totality of the attribute calculate the standard deviation Question 13 Reliability of measurement is defined as __________. frequency of measurement magnitude of measurement accuracy of measurement consistency of measurement Question 14 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. Nominal Ordinal Interval ratio Question 15 The larger the correlation coefficient, _________.Answer the greater the practical significance the smaller its practical significance the larger its range the smaller its statistical significance ÿ
