Document Summary
A great deal of psychology involves some kind of testing. Whether it is the measurement of intelligence, some personality dimension, or simply a questionnaire given as part of an experiment, the test must be properly designed and administered. This section deals with the basics of test construction and the measurement of intelligence in particular. As you read about the various tests remember that every test has limitations. They are not perfectly predictable and in some cases, may be biased: test construction. Whenever we design a test we want it to provide a good estimate of the underlying psychological ability. The instructor designed the test (hopefully) to be a fair assessment of the material to be learned. The same applies to the measurement of psychological abilities. Three of the major concepts to consider are standardization, reliability, and validity. Know how to assess reliability (e. g. , test-retest) and the distinction between content, construct and predictive validity.
