Name two types of construct validity.
|
Convergent and discriminant.
|
|
What method is most useful to assess convergent validity?
|
Multitrait-Multimethod matrix displays the correlations between different tests measuring same and different traits.
|
|
What is criterion-referenced scoring?
|
Pegs performance to some criterion level. A yes or no answer. Pass/fail.
|
|
For timed tests, which measure of reliability is most effective?
|
Alternate forms, becauses measures of internal consistency aren't good, since time is the important variable.
|
|
Correction for attenuation formula
|
Measures the impact on the validity of a test due to an increase in its reliability.
|
|
What is an eigenvalue?
|
A statistic that indicates the variance accounted for by a factor extracted from a factor anlaysis. Used to determine whether a factor should be kept; does it account for a significant amount of variance?
|
|
Kuder-Richardson Formula
|
Used to measure internal consistency of test items.
