Appraisal pt.2 Flashcards
A new IQ test which yielded results nearly identical to other standardized measures would be said to have
A good concurrent validity
Concurrent validity
How well your test stacks up against a well-established test that measure the same behavior.
Convergent Validity
The relationship of a test to an independent measure or trait
Convergent Validity
used to assess a test’s construct/criterion validity by correlating test scores with an outside source
If someone with a snake phobia is exposed to a snake and experience extreme phobia. If they score higher on the test than he would in a relaxed state then it would be called
Convergent Validity
Discriminant Validity
the test will not reflect unrelated variables
When a counselor tells a client that the GRE will predict her ability to handle graduate work, the counselor is referring to
Predictive Validity
Predictive Validity
The power to accurately describe future behavior or events
Criterion Validity
Concurrent and Predictive
A reliable test is ____ valid
not always
A valid test is _____ reliable
always
One method of testing reliability is to give the same test to the same group of people two times and then correlates the scores
Test-retest reliability
Giving the same population alternate forms of the identical test. Each form will have the same psychometric/statistical properties as the original instrument
Equivalent or alternate forms reliability
Which method of reliability testing would be useful with an essay test but not with a test of algebra problems
Interrater/interobserver
A reliability coefficient of 1.00 indicates
A perfect score which has no error
An excellent psychological or counseling test would have a reliability coefficient of
0.90
A researcher working with a personality test discovers that the test has a reliability coefficient of 0.70. This indicates that
70% of the score is accurate while 30% is inaccurate
Using the test-retest reliability method, the correlation between the first and second administration is 0.70. The true variance is
49%.
(0.70 x 0.70)=0.49
IQ means
Intelligence Quotient
____ did research and concluded that intelligence was normally distributed like height and weight and that is was primarily genetic.
Francis Galton
Francis Galton felt intelligence was
A unitary factor
J.P Guilford isolated 120 factors which added up to intelligence. He is also remembered for his
Thoughts on convergent and divergent thinking
A counselor is told by his supervisor to measure the internal consistency reliability of a test but not to divide the test in halves. The counselor would need to utilize
the Kuder-Richardson coefficients of equivalence
The first intelligence test was created by
Alfred Binet and Theodore Simon
Today, the Stanford-Binet IQ test is
a standardized measure
Why is Stanford-Binet standardized?
The scoring and administration procedures are formal and well delineated.
IQ is expressed by
MA/CA x 100
The 9 years old task would be
50% of the 9 year olds could answer correctly
Simon and Binet pioneered the first IQ test around 1905. The test was created to
discriminate normal from retarded Parisian children
Today the Stanford-Binet is used from age 2-adulthood. The IQ formula has been replaced by the
SAS
What is the SAS
Standard age score
