Points and Dimensions
A question has a single Point and a single Negative Multiplier.
You can set the Default Points and Negative Multipliers of the questions in the Question Bank from the Scoring tab in the question editor.
When you add a question to an exam, you can differentiate the Point and Negative Multipliers of the Question in the relevant Exam.
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; affects the following to the same extent:
- Exam Score.
- The score of the section that the questions is in.
- The score of the page that the questions is in.
For example, if the question score 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.
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 the 4 questions completely wrong, the total score of the Exam, Section and Page will be -1. (The situation when 4 wrong answers removes 1 correct answer)
If the Test Score, Section Score and Page Score do not meet your needs, you can create additional Dimension Points.
Dimension points allow you to group and measure a set of questions on the exam, regardless of their section or page within the exam.
Let’s consider in which case you may need 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 Score 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 Dimension contains “/”, the categories 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 dimensions.
