Flashcards in Assessment Deck (24):
Scores from non parallel measures can be equated through the use of:
1. Classical test theory
2. Empirical criterion keying
3. Item response theory
4. Ipsative measures
Item response theory or latent trait theory...calculates to what extent a specific item on a test correlates with an underlying construct. Looks at performance on a test item as rep degree to which have latent trait. Get hard stat ?, have hi stat ability. So can use it to compare performances in 2 measures that have different types or number of items or are scored differently. Use item response theory to develop individually tailored adaptive tests in which to answer one ? In a domain which determines if another ? Will be asked. Such tests have least number of items needed to assess performance.
What is classic test theory?
Views an individuals test score as being the sum of true score variability and error score variability.
X equals T plus E
What is an ipsitive measure?
Only gives info on individual. No info on how they compare.
Performance on vocabulary subtest depends on:
1. Episodic memory
2. Procedural memory
3. Meta memory
4. Semantic memory
4. Memory for facts and concepts.
Procedural...automatic for skills, physical operations...
Meta...persons knowledge or awareness of memory or anything related to storage and retrieval. Ie. knowledge some things easier to remember, or aware on verge of recall...

Never rely alone for differential dx.
Content scales are from content analysis.
