Weighted score of a multiple-choice option with more than one answer [closed]

Question

What would be the formula to calculate the weighted score for the following scenario?

Some question is asked with answer scores ranging from 0 to 5. No correct or incorrect classification. Just a relative score range.

  • Answer 1 Weight = 5
  • Answer 2 Weight = 4
  • Answer 3 Weight = 0

Choice Scenarios:

  1. Highest score if both 1 & 2 are chosen.
  2. Lower score if all 3 options are chosen
  3. Worst score on the choice of 3.
  4. Good (but not the maximum) score if either 1 or 2 is chosen.

I also thought about making the scale -5 to 5 in order to penalize for choosing a negative weight.

Was it helpful?

Solution

Avg weight is 3, score = sum(weight[answers] - avg).

Choose 1, score = 2
Choose 2, score = 1
Choose 1 & 2, score = 3
Choose 1, 2 & 3, score = 0
Choose 3, score = -3
