                        Example 2: Compare as sets

                        Reading time: 1min

                        By default, to be accepted, lists in student and correct answers must have equivalent items and be in the same order. That is, the order is important, and repetition has sense. In contrast, sets are lists without order nor duplicated items.

                        As an example, we can ask for the roots of a given polynomial, and we might be interested in accepting any answer with the correct values.

                        Thus, we can set the lists to be understood as sets in Validation options > Comparison with student answer. That is, ignore repetition and order in the comparison.

                        Besides, we can also define these lists to be understood as sets where repetition matters, but order does not. The grading will behave as you can see below.

                        Student answer Validation
                        {1,2,2}
                        1,2,2
                        1,2
                        1,2,2,2,1
                        122
