Meeting 5: Chapter 8&9 Validity-Estimating and Evaluating Convergent…

- - - - a test should be used only if there is strong enough evidence supporting the intended interpretation and use
    - - operationalism
  - - - the goals of scientific research include describing,predicting, or explaining some aspect of our world, physical/psychological
    - - to the degree that the decisions are based on well validated measures, they hopefully benefit the test user and test takers
- - - - test should include no content that is irrelevant to the construct for which the test is to be interpreted.
    - - test should not include content that is beyond its core contruct, it should include the full range of content thet is relevant to the construct as much as possible
- - - - Many psychological measures are based on assumptions about the processes that people use when com. the measure
      - construct validity --> considering the processes involved in responding to a measure
- - - - test users must be confident that they know exactly which psychological variables are being measured
- - - - only purpose is a good prediction
  - - - most relevant within a research context
- - - - Reveal the general level of validity across all of the smaller individual studies
      - Reveal the variability in validity coefficient among the smaller individual studies
      - Reveal moderators that explain the variability in validity coefficients
  - - - examine and judge the degree to which the patterns gen. makes sense
  - - - 1.heterotrait-momomethod 2. heterotrait-heteromethod 3. monotrait-heteromothod 4.monotrait-Monomethid
    - - correlation produced by shared method variance
