Validity and Reliability - Coggle Diagram

- - - - Accuracy of conclusions drawn from the study
    - - Generalizability of findings to broader populations
    - - How well a test measures the theoretical construct
    - - Ensures the measure covers the full range of the concept
    - - Validity based on correlation with other measures
  - - - Expert reviews
      - Focus groups for feedback
    - - Statistical analyses
      - Factor analyses to evaluate
- - - - The stability of test scores over time when the same test is administered to the same group on two different occasions.
    - - The degree of agreement or consistency between different raters or observers assessing the same phenomenon.
    - - The extent to which items within a test or instrument consistently measure the same construct.
  - - - Correlation analysis for test-retest
      - Inter-rater reliability
      - Cronbach's Alpha for internal consistency.
    - - These coefficients quantify the degree of reliability
      - Range 0 to 1
        
        Closer to 0 lower reliability
        
        Lower than .7 measure may not be sufficiently reliable for research purposes.
        
        Closer to 1 higher reliability
