Reliability and Validity

As part of the test development process, researchers strive to create psychometrically sound instruments with acceptable levels of reliability and validity. When test items are good-fit ones for the construct of an investigation, tests are much more likely to render results that lead to sound decision making than when they are not.

In a minimum of 200 words, respond to the following:

  • Identify the psychometric properties of a test including a description of the various types of reliability and validity.
  • Is it possible for a test to be reliable but not valid? Valid but not reliable?
  • Describe ways in which a test constructor can boost the levels of reliability of a test.
  • Identify a psychological measuring tool (such as a standardized test of intelligence) that has high predictive validity.
  • Explain the pros and cons of using test scores from this measure to make predictions in real-world settings.
