Usage

The Testing-Quest Core App provides a comprehensive set of tools for analyzing and evaluating tests, exams, and questionnaires. Here's a brief guide on how to use its core features:

1. Data Input:

• Ensure your data includes item responses, correct answers, and any relevant metadata.

2. Test Analysis:

• Once data is uploaded, the app will automatically calculate key statistics.
• View the overall "Test Health" score and breakdown of potential issues.

3. Item Analysis:

• Examine individual item performance through the Item Table.

• View detailed item statistics and graphs, including:

  • Item characteristic curves
  • Response distribution
  • Distractor analysis (for multiple-choice items)

4. Visualizations:

• Explore various graphs and charts, such as:

  • Item Map (difficulty vs. discrimination)
  • Reliability curve (Spearman-\Brown prophecy)
  • Score distribution histogram

5. Test Refinement:

• Identify problematic items based on statistical indicators.
• Use the "deactivate" feature to temporarily remove items and re-analyze the test.
• Iteratively improve your test by removing or revising underperforming items.

6. Interpretation:

• Use the app's results to make informed decisions about:

  • Item revision or removal
  • Test length optimization
  • Scoring and interpretation guidelines

Remember to consult the detailed documentation for in-depth explanations of statistical concepts and interpretation guidelines. The Testing-Quest Core App automates the analysis procedures described in the accompanying textbook, providing a powerful tool for test development and quality assurance.
