Statistical expression of relationship between two sets of scoresNumber between -1 & +1
|
|
Coefficent of Determination
|
Aka Shared Variance: square of correlation ; depression and anxiety
|
|
Reliability
|
Consistency; stability; replicability; repeatability of scores*would you score the same if you took the test over, and over, and over agian
|
|
Classical Test Theory
|
Measurement error in every instrumentobserved score= true score+ errorcloser to r=1.0 the less error in the test
|
|
Test- Retest Reliabilty
|
Give the test to same group of people
|
|
Coefficent of Equivalence
|
Parrallel, alternate or equivalent forms (have two forms of the same test)
|
|
Internal Consistency
|
How individual itesm relate to each other and the test as a while*popular choice to establish reliability due to ease of running in statistical programs
|
|
Split-Half Reliabilty
|
Correlate one half of test with other half*use Spearman-Brown to control for shortness of test
|
|
Inter-Item Consistency
|
Average correlation of all of the possible split-half reliabilities
|
|
Inter-Rater Reliabilty
|
Behavioral observations
|
|
Item Response Theory (IRT)
|
Extension of classical test theory looks at the amount of error in the total testI
|
|
Validity
|
The degree to which accumulated evidence supports the intended interpretation of test scores for the intended purpose
|
|
Content Validity
|
Examines whether the content of the test is valid for the kind of test it is
|
|
Face Validity
|
A guick look at the 'face' valuse of questions*tests are not always face valid
|
|
Criterion Validity
|
The relationship between the test and a criterion the test should be related to *concurrent validity & predicitve validity (SAT & ACT)
