Download Solution PDFThe correct answer is - Reliability
Key Points
- Reliability
- Reliability refers to the consistency or repeatability of a measurement tool.
- In the context of the goodness of measures, reliability is a necessary condition, as it ensures that the measurement produces stable results over time or across different scenarios.
- However, reliability alone is not sufficient because a measure can be consistent without being accurate or valid.
- For example, a weighing scale that consistently shows incorrect weight is reliable but not valid.
Additional Information
- Validity
- Validity refers to the accuracy of a measurement tool, i.e., whether it measures what it is intended to measure.
- While validity is crucial, it is dependent on reliability. A measure cannot be valid if it is not reliable.
- Measurement
- Measurement refers to the process of assigning numerical values or categories to variables or traits.
- It is a broader concept and encompasses both reliability and validity as essential components of a good measurement.
- Sensitivity
- Sensitivity measures the ability of a test or tool to detect true positives or changes in the variable being measured.
- While sensitivity is an important characteristic, it is not directly related to the necessity of reliability in ensuring consistent results.
