Intelligence
The capacity to learn from experience, acquire knowledge, adapt to the environment, and solve problems
Standardized procedure
Protocol for
testing that follows the same steps for all test
takers
Norm

can be determined
Mental age

benefit from further training

strongly predicts a person’s performance on a battery of intelligence tests that measure everything from abstract problem-solving to social intelligence.
Standardization
Conversion of scores from the number of correct answers to a relative performance score compared to others on the same test
Reliability
Consistency in measurement
– Test-retest reliability
– Split-half reliability
Test-retest reliability
The likelihood of receiving a
similar score when a test is repeated
Split-half reliability
Performance on one-half of the
test is compared against performance on the other
half.
Validity
The ability of a measure to capture what
was intended
– Content validity
– Predictive validity
– Content validity
Refers to the surface appearance
of the items on the test and whether they reflect the
concept of interest (also called face validity)
– Predictive validity
The ability of a test to identify
those who will have high scores on other measures
