Knowledge Check 2- Staffing and Selection

Obtained scores are comprised of:

true scores and error

What does it mean when someone scores in the 95th percentile on a test?

their score was higher than 95 percent of the people taking the test

If the coefficient of determination is .64, then we know that:

64% of the differences in individuals' job performance can be explained by differences in their test scores

Two individuals' scores on a test should not be considered significantly different from one another unless the difference is:

2 times the standard error of measurement of the test

Which of the following represents one approach to conducting a criterion-related validity study?

Both predictive and concurrent validation are criterion-related strategies

Which of the following is the most important source of information on tests for human resource selection?

Buros' Mental Measurements Yearbook

Research conducted by Barrett, Phillips, and Alexander drew which conclusion about predictive and concurrent validation?

Concurrent validation is probably just as useful as predictive validation for determining the validity of ability tests

What does it mean that the relationship between a predictor and a criterion is statistically significant at the .05 level?

If we conducted our study in the same manner 100 times, we would find a similar relationship between the predictor and criterion in 95 out of 100 of those studies

Which of the following is true? Paper and pencil selection tests never yield interval data Nominal data cannot be statistically analyzed Most selection tests represent ratio scales of measurement Interval data permit more powerful statistical analyses to be performed than ordinal data

Interval data permit more powerful statistical analyses to be performed than ordinal data

Test - retest reliability estimates are most useful for:

ability tests

Which of the following can influence whether concurrent validation is a useful strategy?

all three of the other options influence its usefulness

What is a content validity ratio?

an index computed on a panel of experts' ratings regarding the degree of overlap between the content of a selection measure and the content of the job in question

If the reliability of a test is .81, then we know that the validity of the test:

cannot be greater than .90

For a selection test to be "standardized", it is important to assess the:

content, administration, and scoring of the test

Which of the following is not a classical approach that can be used to validate measures used in selection?

face validity

Which of the following measurement scales ranks objects from "high" to "low" on a variable of interest?

ordinal

Which of the following IS NOT an estimate of internal consistency? parallel forms reliability Coefficient Alpha split-half reliability Kuder-Richardson reliability

parallel forms reliability

Which type of validation strategy is most influenced by sample size?

predictive validity

Consistency of measurement is most closely associated with:

reliability

"Level B" tests:

require some formal training of testing concepts to be properly scored and interpreted

Which of the following symbolically represents a validity coefficient?

rxy

Cross validation is necessary because of the effects of ______ on predictive accuracy.

shrinkage

In which type of validation are selection measures validated across several jobs in an organization rather than using only one job?

synthetic

Precision in measurement refers to:

the number of distinct scores permitted by the measure that is being used

What does the correction for attenuation formula show?

what the true variance in test scores would be if their range was not restricted
