Description

With reference to #12544, it is possible to add empty weights (i.e. Leave the input box for weight empty) for rubric questions. The issue demonstrates that empty weights can be a valid feature. They can be used for:

• Rubric options that do not have a suitable numerical weight
• Rubric options that the user does not want to be calculated in the average weight statistics

Weights are also present in MCQ (single answer) and MCQ (multiple answers). However, both question types currently do not allow users to save with empty weights:

Should empty weights be allowed for MCQ (single answer) and MCQ (multiple answers) too? Here's a possible use case:

• Question: "Do you think this class is helpful?" with the options of:
  • Not enough information to evaluate
  • Disagree
  • Agree

It's difficult to assign a numerical weight to the 1st option.

Suggested Solution

• You may wish to refer to [#12544] Rubric Question Statistics: Handle empty weights #12545
  • Use - to represent empty weights
  • Skip over empty weight values when calculating average weight
    • Edge case: All options have empty weights -> Average/total cannot be calculated -> Represented by -
  • Add explanation on usage of empty weights
