Study Notes
Types of Reliability
- Test-Retest Reliability: Consistency over time, ensuring that results are similar when the same test is administered on different occasions.
- Inter-Rater Reliability: Consistency across people, ensuring that different raters or observers agree on the results.
Concept of Reliability
- Reliability in Measurement: The consistency of a measure or instrument in producing similar results under consistent conditions.
Difference between Reliability and Validity
- Reliability: Consistency of a measure, does not necessarily imply accuracy.
- Validity: Accuracy of a measure, ensuring that it measures what it is intended to measure.
Example of Reliability vs. Validity
- Reliable but Invalid Measurement: A measurement that consistently produces the same inaccurate results, e.g., a faulty thermometer that always shows the wrong temperature, but consistently shows the same wrong temperature.
