Moodle 3: Activities & Resources: Quiz Question Types: Numerical

Numerical questions allow for a numerical response, possibly with units, that is graded by comparing against various model answers, possibly with tolerances. For example, if the answer is 30 with an accepted error of 5, then any number between 25 and 35 will be accepted as correct.

You are able to

  • grade the number and the unit independently,
  • choose to handle the unit response either as
    • a text input element or as
    • a multichoice radio element,
  • just grade the number with the option to write the unit close to the input element,
  • put the unit either
    • at right of the number as the most common occurence
    • or at left as in $ 100,000.

Your valid number formats and specific instructions on how to answer will be put near the answer input element.

Questions may have different answers with different levels of accuracy. That lets you create questions like "What is a root of x^2 - 3x + 2?" and award different levels of credit depending on the accuracy of the answer.

5. General Settings include a Question name, Question text and Default mark which are required. Optional settings include Category and General feedback.

NOTE: It is suggested that the instructor make sure that the category is correct for organizational reasons and that the question name be something specific (other than Number 1) so that it is easier to find and edit them later.

6. In the Answers section, enter the accepted answer(s). Note: Floating point numbers, e.g. 23.4, may also be written as 23,4 or 2.34E+1. You will also need to enter an accepted error for this answer. This is the range above or below the answer that Moodle will accept as a match. For example, if the correct answer is 5, but you will accept 4 or 6, your accepted error is 1.

Enter a grade and feedback for the accepted answer and repeat for each additional answer you want to accept as correct. You can provide feedback for all wrong answers by using the asterisk character (*) as an answer with the grade of 'None'.
