New Test questions Flashcards
Lord’s Chi-squared
used to assess differential item functioning (two groups respond differently to item when they both should respond the same)
Differential item functioning
two groups respond differently to test item when in fact they should be responding similarly-important for item response theory
item response theory
theory about measuring latent traits and manifestations (ie unobservable or difficult to observe traits)
Unit of analysis comparison between classical and item test theory
Classical-test is unit of analysis
IRT: item is unit of analysis
Classical and IRT comparison?
CTT: comparisons can only be made when tests/measures are parallel
IRT: comparisons can be made when item measures same latent trait
CTT and IRT and representative samples and item properties
CTT: depend on representative samples
IRT don’t depend on representative samples
IRT standard error of measurement
larger for those with very high or low ability
CTT IRT latent trait continuum
CTT: Compares scores of test measure with scores of reference group
IRT: compares distance on items on the ability scale
response categories for IRT and CTT
IRT: can have different response categories for different items (yes no, likert, strongly agree, etc)
CTT response category must be consistent.
ITR assumptions
4 assumptions
Monotonicity: trait level and probability of correct response increases
unidimensionality assumes there is one response/latent trait measured
local independence: each item stands on its own
Invariance – We are allowed to estimate the item parameters from any position on the item response curve
Using examples of patients in class/supervision
standard 4.07 prohibits psychologists from using confidential, information about their clients unless they have taken reasonable steps to remove all personally identifiable information. Simply using a pseudonym is not sufficient, when other details have not been changed.
