Psych testing ch 5

QuestionAnswer
What is required in testing a tests worthiness? Validity, reliability, cross cultural fairness, and practicality.
What is test worthiness? How good a test really is.
Correlation coefficient The relationship between two sets of test scores. It is a statistical concept used in discussions of critical factors listed.
Scatterplot A graph showing two or more sets tests scores.
Coefficient of determination Factors that take into account the relationship for the two variables. Square of correlation ( r squared).
Validity How well does a test measure what it is supposed to measure.
Content validity Is the content of the test valid for the kind of test that it is?
face validity Not an actual type of validity. Has to do with how a test superficially looks.
Criterion related validity A test that measures how well a test predicts or correlates with a certain outcome.
Concurrent validity When a test is shown to be related to an external source that can be measured at around the same time the test is being given.
Predictive validity Relationship between test scores and a future standard. Evidence that test scores are able to predict future standards and criterion.
What are the two types of criterion related validity? Concurrent validity and predictive validity
Construct validity The scientific basis for showing that a construct (idea, concept, model), such as intelligence is being measured by a test.
Experimental design validity Using experimentation to show that a test measures a concept.
Factor analysis A way to show construct validity by examining the relationship between sub scales and the larger construct.
Convergent validity When there is a correlation between a test and other tests that are similar.
Discriminating validity Shows that there is little two or no correlation between a test and other tests.
Reliability Freedom and constancy of measurement.
Test retest reliability The relationship between scores from one test that have been given to two different administrations.
Alternate forms reliability The relationship between scores from two similar versions of the same test.
Internal consistency Reliability measured statistically by going within the test.
Split half reliability When a test is split into two parts and a persons score on both parts gets compared.
Coefficient alpha Reliability based on mathematical comparison of individual items with one and another and a total score.
IRT (Item Response Theory). Examines each item for its ability to discriminate as a function of the construct being measured.
Cross cultural fairness Degree to which cultural background, class, disability, and gender do not affect test results.
Practicality Feasibility considerations in test selection and administration.
Mental measurements year book (MMY) A commonly used resource that is helpful in finding and selecting tests, instruments and screening devices.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
