Answer :
Final answer:
The appropriate test to determine the internal reliability of a survey is the test-retest reliability method. This process tests whether the survey results are consistent when it is administered multiple times over a certain timeframe. IQ tests, SAT tests, and blood pressure tests are types of test, not methods for testing reliability.
Explanation:
In order to test the internal reliability of a survey, the appropriate choice would be Test-retest reliability. This refers to the degree to which the outcomes of a particular measure remain consistent over multiple administrations. In other words, if you were to administer the survey multiple times over a certain period, the results should be relatively consistent if the survey has good test-retest reliability. For example, when the Minnesota Multiphasic Personality Inventory (MMPI) was given again to the same police officers two years later as in the experiment by Beutler, Nussbaum, and Meredith (1988), the results should show similar indications, assuming changes in conditions are not too drastic. Options a) IQ test b) SAT test and d) Blood pressure test are inappropriate because they are specific types of test rather than methods of testing reliability. To conclude, testing the internal reliability of a survey is crucial to ensure that it produces consistent, reliable data, regardless of when it is administered, and test-retest reliability is an important method to use for this purpose.
