|
validity |
how well a test measures what it is supposed to measure |
|
|
inference |
logical result or deduction |
|
|
validation |
gathering evidence about validity |
|
|
face validity |
a test appears to measure what it actually measures |
|
|
consequences of low face validity |
lack of confidence in perceived effectiveness of the test
decrease in test takers confidence and cooperation
|
|
|
content validity |
degree to which a test measures what it is supposed to measure
ex: low content validity if spelling problems are on a test for math |
|
|
test blueprint |
plan regarding the types of information to be covered, number of items, organization, etc |
|
|
culture and relativity of content validity |
history and politics |
|
|
criterion validity |
degree to which a test measures the thing you want it to measure, based on comparison of your scores with scores of a different test |
|
|
two types of criterion validity |
concurrent and predictive |
|
|
concurrent validity |
degree to which a test score is related to some measure obtained at the same time |
|
|
predictive validity |
degree to which a test score predicts some criterion measure |
|
|
criterion |
standard against which a test or test score is evaluated |
|
|
incremental validity |
degree to which an additional predictor explains something about the criterion measure that is not explained by the predictors already in use |
|
|
construct validity |
degree to which a test measures a construct-about the idea, concept |
|
|
construct validity: changes with age |
some constructs change over time and test should also reflect those changes |
|
|
evidence of pretest-posttest changes |
test scores can change as a result of some experience |
|
|
rating error |
judgment resulting from the intentional or unintentional misuse of a rating scale |
|
|
leniency error |
error that occurs from the rater being lenient in scoring |
|
|
severity error |
error that occurs from the rater being severe |
|
|
central tendency error |
rater is reluctant to give an extreme positive or negative score
ratings will cluster in the middle |
|
|
halo effect |
some ratees can do no wrong
rater shows favorability |
