Testing -MT- Chapter 5 Flashcards
1
Q
Reliability Coefficient
A
- Allows to compare reliability of diff tests
- ideal coefficient = 1 (precisely same results for part. set of cand.)
- 0 = results unconnected
- b/w 1-0 genuine test
- higher for High Stake
2
Q
Reliability coefficient methods
A
- Take test twice
- Split half Method
3
Q
Candidate true score
A
Evaluate the standard error of measurment
- score that represent ability vs. actual score
4
Q
Increase reliability
(for t-takers)

- Take enough samples of behaviour (+item, fresh, notboring)
- Candidates = No freedom
- Write unambiguous items (1answer, ask collegues)

- Legible
- Familiar Format

- Make comparison direct (no freedom)
- Detailed scoring key + Train scorer
- Agree on appropriate before scoring
- Identify candidates by numbes
- multiple independant scoring (3, 2 + 1 compare)
6
Q
Reliability Vs. Validity
A
Duality
- 0 reliability = 0 validity
- ++ reliability = – validity
