In the previous tutorial in on Inserting a Calculated question in the Moodle Question Bank<\/a>, there was a setting called Tolerance<\/strong>. The Tolerance<\/strong> of a question is used to allow answers to be correct, even if they are close to the correct answer. For example, if a math question is 2.3 x 2.011<\/strong>. The correct answer is 4.6253<\/strong>. If the student answers 4.63<\/strong>, the tolerance can accept that answer as correct, even though its not the exact answer. This is similar to \u201cGrading on a curve<\/em>\u201c. This tutorial will explain using the tolerance in the Moodle 2.3 calculated question.<\/p>\n

Setting the Tolerance for a calculated question<\/h3>\n
    \n
  1. Log into the Moodle Dashboard<\/a><\/li>\n
  2. Navigate to the Front page settings<\/strong> > Question bank<\/strong> > Questions<\/strong>. Click one of the calculated questions that were created. If there are no calculated questions create one<\/a>.<\/li>\n
  3. \"calculated-tolerance\"<\/a>\n
    <\/div>\n

    On the Editing a Calculated multichoice question<\/strong> page, go to the Answer <\/strong>section. The following chart will explain the different tolerances.
    <\/p>\n

    Note!<\/strong> The tolerance is designed to match the answer with a specific parameter. An answer of 15.7<\/strong> can be answer as 16<\/strong>, 27<\/strong> as 30<\/strong>, and or 50<\/strong> as 50.0<\/strong> and so forth. For example, a Nominal tolerance with the correct answer as 100<\/strong> and the tolerance as 0.01<\/strong>, the Formula will be (100)*(0.01) <=1<\/strong>. The tolerance is <= 1<\/strong>. So the answer will be correct if its between 99<\/strong> and 101<\/strong>.<\/p>\n


    <\/p>\n\n\n\n\n\n\n\n
    Calculating the tolerance type for correct answers<\/th>\n<\/tr>\n
    Tolerance<\/strong> = T<\/span>
    Correct Answer<\/strong> = c<\/span>
    Tolerance\u00b1=<\/strong> = X<\/span><\/td>\n<\/tr>\n
    Nominal<\/strong><\/td>\nThe Nominal tolerance will mark an answer correct if the answer is within the parameters of X<\/span>c<\/span> <=T<\/span>.<\/td>\n<\/tr>\n
    Relative<\/strong><\/td>\nThe Relative tolerance will mark an answer correct if the answer is within the parameters of X<\/span>c<\/span> \/ c<\/span> <= T<\/span>.<\/td>\n<\/tr>\n
    Geometric <\/strong><\/td>\nThe Geometric tolerance will mark an answer correct if the answer is within the parameters of X<\/span>c<\/span>2<\/sup> \/ c<\/span>2<\/sup> <= T<\/span>2<\/sup><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n


    <\/p><\/li>\n

  4. \"calculated-tolerance-final\"<\/a>\n
    <\/div>\n

    Finally, preview the question. The answer should look like the following snapshot. The Tolerance is something that will need to be expirimented with to find the perfect setting for each question.
    <\/p><\/li>\n<\/ol>\n

    This concludes the article for Working with the calculated question Tolerance. Please check the next article on Adding a Calculated multichoice question in the Moodle Question Bank<\/a>.
