Foundations of Testing
A test that suggests you have strong spatial reasoning, which may indicate potential success in engineering or architecture.
What is: an aptitude test
Height, Weight, Age, and Income are examples of this level of measurement
What is: ratio
The formula X = T + E represents this theory
What is: classical test theory
Experts rating whether items are essential provides this type of evidence
What is: content validity evidence
In Y′ = a + bX, b represents
What is: the slope
The three elements common to all psychological tests.
What is: Psychological construct, behavior, inference
If most students scored very high and only a few scored low, the distribution is this type of skew.
What is: negative skew
If two observers code aggressive behavior, this type of reliability is required.
What is: Inter-rater reliability
Low correlation with an unrelated construct provides this type of evidence.
What is: discriminant validity evidence
In a multiple regression, if two predictors correlate at r = .89, including both likely causes this issue.
What is: multicollinearity
A decision where a student is dismissed if GPA falls below 2.0
What is: an institutional absolute decision
Describe the strength and direction of this correlation coefficient: r = .90
What is: very strong, positive relation
A student’s observed exam score fluctuates slightly each time they take the same test, even though their ability has not changed. This fluctuation represents this component of Classical Test Theory.
What is: Random measurement error
Strong correlation between a new anxiety measure with another anxiety measure provides this type of evidence.
What is: Convergent validity evidence
Testing whether items load on three predicted factors uses this procedure.
What is: confirmatory factor analysis
objective vs subjective: A test that uses structured true/false questions to assess someone's intrinsic motivation.
What is: an objective test
If r² = .25, what is the percentage of shared variance?
What is: 25%
A scale contains items measuring anxiety, depression, and stress. Cronbach’s alpha is calculated for the entire test. The estimate may be misleading because the test is this.
What is: Multidimensional
If a job screening test predicts future job performance, this type of validity is demonstrated.
A new statistics aptitude test is designed to predict success in a statistics course. However, final grades also include participation and attendance, which are unrelated to statistical ability. The criterion (success in the course) is now affected by this issue.
What is: criterion contamination
If you administer a depression test and combine it with clinical interview data and treatment history to reach a diagnostic conclusion, you are engaging in...
What is: an assessment
A score that is -3 SD units below the mean represents this type of performance.
What is: extremely low, much worse then the rest of the sample
If a test–retest reliability coefficient is low, one possible explanation is that the construct being measured is not this.
What is: Stable over time
A math placement test is administered during orientation. That same afternoon, students take an established standardized math exam. The strong correlation between the two demonstrates this type of evidence.
What is: concurrent validity
In a pattern matrix, the item with the highest loading on a factor represents this.
What is: The strongest indicator of that latent factor
