Numerical quiz question

Add a numerical question to pose a mathematical question that requires a specific numerical response and set an error tolerance (see below) higher and/or lower than the answer. You can add a number of correct answers offering different levels of accuracy and a corresponding score for each.

If units are required as part of an answer a penalty can be applied to a learner's score for not selecting the correct unit.

Learners can include the units in the free text field when entering the number or create a multiple choice selection of units for the learner to choose from, which will display as radio buttons or a dropdown menu.

Tolerance

You can set the acceptable tolerance for error within the learner's response and the type of tolerance allowed. The specified tolerance value and the tolerance type selected combines to generate a range of acceptable scores.

If tolerance = t, correct answer = x and the difference between the user's answer and the correct answer is cx, then the tolerance types are as follows: 

• Nominal: Mark correct if cx <= t 
• Relative: Mark correct if cx / x <= t 
• Geometric: Mark correct if cx² / x² <= t²
