Validity - Types.

1. Content validity (Quantitative)

   • Relies on logic and comparison.
   • Must measure all the aspects of what you want to know.
   • Weakest type of validity (multiple choice like question)
   • EXAMPLE: working in swimming Australia and wanting to identify talented swimmers; test measures to be conducted: Swimming test (trial test, duration, intensity).

2. Criterion validity (Quantitative)

   • Correlating scores for test to be specified criteria that accurately measures the same property or attribute of interests.
   • EXAMPLE: expert ratings, actual participation, previously validated test.

3. External validity (Quantitative)

   • Ability of results to be generalised.

4. Concurrent validity (Quantitative)

   • New test is measured up against an established test. E.g: Beep test and sub-max aerobic test.

5. Predictive validity(Quantitative)

   • Score match up with some type of measure in the future.
   • Longitudinal; strongest type of validity.
   • EXAMPLE: Time trail pre competition and ATAR score.

6. Ecological validity (Quantitative)

   • Testing situation must be similar to real-life situation that is being studied.

7. Trustworthiness : Qualitative

   • Use of various forms of data to validate the trustworthiness of the data
   • EXAMPLES: Interview, document analysis, observation.
