variable that is manipulated
response measured after manipulation of the independent variable
behavior changes because someone knows they are being studied
studies 2 or more variables to determine if they are related
# representing strength of relationship between variables, ranges from 0 (no relationship) to 1 (perfect relationship)
makes cause and effect relationships, researcher has control
study of real-world behavior, can determine relationships
gathers information in natural settings
intensive information gathered about individuals
Large amounts of info gathered from many people in short amount of time
objective standardized measure of sample behavior
defining meaningful scores by comparison with the performance of a pretested standardization group.
Where the test condtions, insturctions and materials must be identical to produce the same responses.
established standards of performance for a test
a figure that indicates the percentage of people who score below the score one has obtained
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting
test administered in 2 halves, scores compared
two similar tests administered on two different occasions
numerical index that represents degree of relationship between two variables
the degree to which the content of a test is representative of the domain its suppose to cover
The degree to which test scores indicate a result on a specific measure that is consistent with some other criterion of characteristic being assessed; also known as predictive validity
The success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between test scores and the criterion behavior.
The degree to which a research tool correctly reflects what it is purposed to measure
The extent to which there is evidence that a test measures a particular hypothetical construct.
