Points and Dimensions
A question has a single Point and a single Negative Multiplier.
You can set the default Point and Negative Multiplier of each question in the Question Bank from the Scoring tab in the Question Editor.
When the user answers a question, he first gets a Success Rate over 100%. The success rate must be between -100% and 100% . We have explained how the success rate of the question is calculated in the Multiple Choice Question section.
User’s Success Rate gained from the question:
- If positive, the relevant success rate is multiplied by the Question Point.
- If negative, the relevant success rate is multiplied by the Negative Multiplier.
The result of the multiplication affects the following to the same extent:
- Exam Score
- The score of the section that the question is in
- The score of the page that the question is in
When the Question is Answered Correctly
For example, if the question's point is 2 and the user answered the question with complete success (100%), the Exam Score, Section Score and Page Score (100% x 2) are increased by 2.
When the Question Is Answered Wrong
Negative Multiplier is zero by default. In this way, if the user answers the question incorrectly, the Exam Score, Section Score and Page Score are not affected.
However, for example, if the Negative Multiplier is set to -0.25 and the user has achieved -100% success by ticking the wrong options in the question, the Exam Score, Section Score and Page Score are reduced by -0.25 (-100% x 0.25). According to this example, if the user answers 4 questions completely wrongly, the total score of the Exam, Section and Page will be reduced by -1. (The situation when 4 wrong answers removes 1 correct answer)
Dimensions (Also known as Category Point)
If the Test Score, Section Score and Page Score do not meet your needs, you can create additional Dimension Points.
Let's consider in which case you may need a Dimension Points. For example, you have an exam and you want to measure the first question of page 1 and the last question of page 3 separately. In this case, you can define Dimension Points for the related questions
As another example, you might want to measure a group of questions in your exam by grouping them into the Numeric category under the Reasoning category.
To do this, again go to the Scoring tab in the Question Editor and select the Additional Point Calculations option. Then type the name of the dimension and identify the Points and Negative Multipliers next to it.
If the name you specify for the Category (also known as subject or dimension) contains "/", the dimensions are calculated as a Tree Structure. In the example above, Reasoning/Numerical is written as Dimension Name. In this case, success from the relevant question will affect both the Reasoning and the Reasoning/Numerical categories (dimensions).
