Study Notes
Observational Techniques and Reliability
- Assessing reliability in observational techniques involves calculating inter-observer reliability using a correlation coefficient from observers' data; a score of 0.80 or above indicates good reliability.
- Inter-observer reliability measures the agreement among multiple observers when assessing the same behavior.
Fundamental Concepts of Reliability
- Reliability refers to the consistency of measurements across different instances.
- Test-retest reliability evaluates whether results are consistent when the same measure is applied on different occasions.
Importance of Assessing Reliability
- Evaluating reliability in observational methods is crucial due to potential biases from observers, ensuring that the data released is trustworthy and does not cause harm.
Enhancing Reliability in Observations
- To improve reliability, observers should further operationalize categories and receive more practice in applying these categories.
Validity Assessment in Self-Report Techniques
- Test-retest methods assess validity by administering the same test to the same participants on two occasions, allowing time for forgetting. Similarity in scores indicates higher reliability.
- Inter-interviewer validity compares responses from the same participant with different interviewers or the same interviewer over a week apart.
Improving Reliability of Self-Report Techniques
- Reducing ambiguity in questions is vital, as unclear questions can lead to varying interpretations that affect data consistency.
Reliability in Experimental Settings
- The reliability of experiments focuses on maintaining consistency in methods used throughout the experiment.
Enhancing Experimental Validity
- Standardization ensures that procedures are uniformly applied to all participants, allowing for valid comparisons of results.
