2.2.11.8 Numerical Question

To add a numerical question, make sure “Numerical” is selected in the “Create new question” pull-down menu. This will take you to the numerical question screen:

A numerical question is a question that expects a number for the answer. It has the added flexibility to accept a range of answers (10 +- 3 would accept anything from 7 to 13). Fill in the “Question name” with anything that will help you identify the question. In the “Question text” box, fill out the question you wish to ask (“How fast can Matt run?”). If you have loaded any picture images to the system (in the “Files” section from above), you will have the option to display the image as part of the question. You may also set the default number of points assigned to this question and a Penalty factor. You then fill in the correct answer (10 in my example) and the accepted error (2 in my example would allow a correct answer of 8-12). You may then fill in feedback if you wish to use that feature.

Note that you can have multiple answers. This might work well for a question like “Identify one of the first odd-numbered 5 prime numbers”. Then, you could give a grade of 100% for the answers “1”, “3”, “5”,“7” and “11”. And maybe you’d give a grade of 50% for the answer “2”… since it is one of the first 5 primes… but it’s not an odd number.

There are also optional fields to add units (like meters, kilograms, etc.). You may also add additional units with the appropriate conversion multiplier. For example, if your main units were meters, you could also add a multiplier of 100 with the units of centimeters. IMPORTANT: If you add units, the question will be wrong if the student does not give the exact units. For example, 10 kph and 10 k.p.h. are different answers because the units are different (spaces are okay – 10kph and 10 kph are the same). When everything is filled out the way you want it, click on “Save changes.” The question will then appear in the list of questions.
