Question #1
Which of the following is NOT true about reliability?
A.
The observed reliability score is computed from a true score plus error score.
B.
All these are true.
C.
Unreliable measures produce results that are meaningless.
D.
Reliability is not estimated, it is measured.
E.
There are multiple sources of error
Question #2
Which of the following is NOT true about Cronbach's alpha (one form of internal consistency reliability)?
A.
Cronbach's alpha is the most popular measure of internal consistency.
B.
For widely used scales, the Cronbach's alpha should .80 or above.
C.
In general, more items in a scale results in a higher Cronbach’s alpha.
D.
All these are true.
E.
Cronbach's alphas range from 0-1, with scores closer to zero indicating lower reliability.
Question #3
Which of the following is NOT true about Cronbach's alpha (one form of internal consistency reliability)?
A.
A Cronbach's alpha score is generally lower than the actual reliability, thus, it is considered a conservative estimate.
B.
For an exploratory study, a Cronbach's alpha above .70 is considered acceptable.
C.
Cronbach's alphas are often used for Likert-type scales.
D.
For standardized test scores, a Cronbach's alpha of .90 or greater is recommended.
E.
All these are true.
Question #4
Which of the following is NOT true?
A.
A split-halves reliability assesses whether scores on half the items relate to scores on the other half of the items.
B.
All these are true.
C.
An omega coefficient is probably better with ordinal level data than a Cronbach's alpha.
D.
A parallel form reliability assesses whether two different scales of the same construct are related to each other.
E.
A Kuder-Richardson reliability is designed for scales using dichotomous items.
Question #5
Which of the following is NOT true?
A.
All these are true.
B.
Construct validity is the most rigorous validity test
C.
Because face validity is so basic, it can be skipped.
D.
Expert opinion is often used to establish content validity
E.
Content validity assesses how well the items represent the entire universe of items from which they are drawn

A.
Construct validity
B.
Convergent validity
C.
Interrater / Interobserver reliability
D.
Content validity
E.
Face validity
Question #14

A.
Concurrent validity
B.
Internal consistency reliability
C.
Predictive validity
