intellegince Flashcards
Intelligence
All-purpose ability to do well on cognitive tasks, to solve problems, and to learn from experience.
g factor
refers to the existence of a broad mental capacity that influences performance on cognitive ability measures
Validity
refers to the ability of a test to measure what it was designed to measure
internal validity
the degree to which the results are attributable to the independent variable and not some other rival explanation.
external validity
the extent to which the results of a study can generalization.
face validity
the degree to which a procedure, appears effective in terms of its stated aims.
content validity
how well a measure effects the entire range of material it is supposed to be testing.
Criterion related validity (concurrent validity)
how much of a characteristic a person has now.
Criterion related validity(predicitive validity)
measures future perfomance.
Constructive validity
is the degree to which a test measures what is claims, or purports to be measuring.
Reliability
the extent to which a test yields a consistent, reproducible measure of performance.
split-half reliability
test is split into two, each half is tested, if the scores are consistent, then the test is reliable (the closer the correlation is to +1, the more reliable)
Equivalent form reliability
the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same subject.
test retest reliability
administering the same test twice over a period of time a group of individuals. The scores from Time 1 and Time 2 can be then correlated in order to evaluate the test for stability over time.
Standardization
The development of uniform procedures for administering and scoring a test, and the creation of norms (performance standards) for the test.
