Item Analysis Timing for Tool Standardization
Item analysis is a crucial step in standardizing a tool, especially when using the Likert Summated Rating technique. This process helps evaluate the quality of individual items within the tool.
Rationale for Timing
- Data Requirement: Item analysis involves examining how individual items perform with respect to the overall scale or construct. This requires actual data collected from respondents.
- Trial Test Necessity: A trial test (or pilot study) on a small group of subjects is conducted specifically to gather this initial data.
- Evaluation Metrics: After the trial test, the data is analyzed to calculate metrics like item difficulty, item discrimination, and item reliability. This analysis informs decisions about which items to keep, modify, or discard.
- Likert Scale Context: For Likert scales, item analysis ensures that the selected items contribute effectively to measuring the intended attitude or trait consistently.
Therefore, item analysis is performed after the trial test on a small group of subjects, using the data obtained from that test.
The correct option is: After the trial test on small group of subjects.
