User Story

As a user of the learning curve point info details feature, I want to see the frequency of each item in the detailed list of items (KCs, students, problems, steps), so that I can see the difference more clearly.

Notes/Comments

  • Ken, Meeting 7/10/2009: In the learning curve point info details, have a column that gives the frequency (% the number of observations divided by the total observations) or just the number of observations. Maybe showing 'Observations' is best as the title is easy to figure out.
    • Example: Geometry 96 dataset, zoomed in circle-area, at opp 5, which steps...go back one opp, what's the difference.
