1. Evidential 2. Consequential |
|
|
What is Face Validity? |
test is obvious to test taker, subjective, affects how people respond to the test |
|
|
What is Content Validity? |
does it represent what you were trying to measure? |
|
|
What are the 3 steps in developing content valid tests? |
1. a well-defined construct 2. domain sampling questions 3. expert ratings of items or Lewshe's Content Validity Ratio |
|
|
What is Criterion-Related Validity? |
the standard to which a test is evaluated |
|
|
What is Concurrent Validity? |
degree to which a test score is related to a criterion measure obtained at the same time |
|
|
What is Predictive Validity? |
degree to which a test will predict scores on some future criterion uses Pearson's R as the measure |
|
|
What is Incremental Validity? |
does test predict any additional variance than what has been previously predicted by some other measure venn diagram example |
|
|
What is Convergent Validity? |
does our measure highly correlate with other tests designed to measure the same construct? |
|
|
What is Discriminant Validity? |
does it not correlate with measures |
|
|
What is a Base Rate? |
extent to which a particular trait or characteristic exists in the population |
|
|
What is a Hit Rate? |
proportion of people accurately identified as possessing or exhibiting some characteristics |
|
|
What is a Miss Rate? |
proportion of people the test fails to identify as having or not having particular characteristics |
|
|
What is a False Positive? |
when you hire someone who is not actually qualified |
|
|

|
|

proportion of the population who will meet the criteria |
|
|
When using the Taylor Russel Table, what does the Selection Ratio represent? |
the proportion of the population selected |
|
|
What is the difference between unfair and biased? |
bias is systematic and inherent |
|
|
What is the difference between Concurrent and Predictive Validity? |
Concurrent: test score is related to a criterion measure obtained at the SAME time Predictive: degree to which a test score predicts scores on some future criterion |
|
|
What is the difference between Convergent and Discriminant Validity? |
convergent--how tests relate to construct discriminant--how tests are dissimilar |
|
|
How is Cronbach's Alpha calculated? |
take the average of all of the split-half reliabilities |
|
|
If the reliability of a test increases, what would happen to the SEM? |
decreases |
