Similar to a short-answer question that features numerical answers with an accepted error.
From the student perspective, a numerical question looks just like a short-answer question. The difference is that numerical answers are allowed to have an accepted error. This allows a fixed range of answers to be evaluated as one answer.
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 independently the number and the unit,
- Choose to handle the unit response either as
- A text input element or as
- A multi-choice 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 $ 100,00.
Furthermore your valid number formats and specific intructions on how to answer will be put near the answer input element. An example
Numerical multiple choice unit example:
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.
