lightbulb_outline This question type can be used in a digital test only.

A numerical question can be used to limit the student’s answer to a number. You can specify the answer and margins to review automatically. A numerical question can be a question with a value or a question consisting of variables.

Questions can be created either in a question bank exercise or from within a course assignment. The video below demonstrates creating the questions from the question bank exercise.

Create a numerical question with a value

To create a numerical question with a value, follow the steps below.

  1. Navigate to your question bank or your course assignment. 
  2. Click New exercise, fill in a name and click Save.
  3. Click New question and select Numerical question.
  4. Formulate the question in the question content field.
  5. Fill in the number of points the question is worth.
  6. Fill in the value. Optionally, fill in the margin.
  7. Click the dropdown menu Margin type and select % or Absolute. 
  8. Click the more_vert-icon for more options.
  9. Click Save.

Create a numerical question with a variable

To create a numerical question with a variable, follow the steps below.

  1. Navigate to your question bank or your course assignment. 
  2. Click New exercise, fill in a name and click Save.
  3. Click New question and select Numerical question.
  4. Fill in the number of points the question is worth.
  5. Click the more_vert-icon and select Use variable.
  6. Click the more_horiz-icon and select Code editor.
  7. Use the script editor to create your variables. The coding language used is Python.
  8. When all variables are defined, click Run to run the code. To check if the variables are defined correctly, you can use print statements to check the values of the variables you have defined. This way, if running the code gives an error, mistakes can be found.

Options for a numerical question

For additional options, click the more_horiz-icon and click Edit. Then click on the more_vert-icon. You will see the following:

  • Bonus
    This marks the question as a bonus question, which means that its points are not included in the maximum amount of points achievable for that assignment. If a student answers the question incorrectly, this will not be detracted from the number of points and the mark. However, when awarding points, it is possible to achieve more points that the maximum points achievable for the assignment.
Add a grading scheme to a numerical question

To add a grading scheme to a numerical question, follow the steps below.

  1. Click the Grading scheme tab at the top of your assignment or question bank exercise.
  2. Go to the question for which you want to set the grading scheme.
  3. Click the more_horiz-icon and click Edit. 
  4. Fill in the number of points.
  5. It is optional to fill in feedback that is shown when the results are published for:
    • the question is answered correctly
    • the question is answered incorrectly
  6. Click the more_vert-iconfor more grading options.
  7. Click Save.

Options for grading a numerical question
  • Model answer
    A solution for the reviewers (and for participants when published). The model answer can be an extensive elaboration, an image, or a file.

  • Start with zero points
    If this option is enabled the marking of this question will always start at zero points and the points will be added up when selecting the criteria. When this option is disabled, the marking will begin with the maximum amount of points that can be awarded for this question and selecting the criteria will be subtracted from this maximum. This means that the criteria should be added as minus points of the total amount. The reviewer can then select the criteria if the student did not meet this with their answer, so it can be detracted from the total amount of points.

  • Limit minimum to zero points
    With this option enabled, it’s impossible to go below zero points when selecting the different criteria. It is still possible to manually adjust the number of points to go below zero with the adjustment option during the reviewing.

  • Limit maximum to total points
    In the grading settings it’s possible to set the maximum amount of points achievable with the question, separate from the points per criteria. When this number deviates from the maximum amount achievable by adding up the criteria points, this option will cap the maximum amount of points to this manually set number.
