Aside from the grade distrbution charts, the new Result Analysis section will have a sub-section for Assessment Metrics.
This will show an overview of all items within a folder and its subfolders that contribute to the grade.

Assessment metrics

The overview shows:

  • flattened weight for each item (= its effective weight on the “total” folder context)
  • for each item:
    • rir value
    • p-value
    • mean-score
    • std
    • Cronbach’s alpha (for context folder), and delta Cronbach’s alpha for each item

Furthermore, it highlights values when they need attention and shows hints what might be causing problematic values.

p-value distribution

A second section shows 2 graphs to llustrate the distribution of items per difficulty level (range of p-value) with examples of well and poorly balanced tests.
