Good evening,
I have 2 answers in part 1 Answer* field of Moodle Formulas as [5, 10].
Now 5 is answered correctly, but 10 is answered incorrect. So, both are marked as incorrect or given zero score.
Please is there away to mark one correct and say given 50% scores?
I already know how to use Part 1, Part 2, etc, but I have up to 16 combined answers so trying to avoid the part1, part 2, part 3, individual answers.
Many thanks.
Dipo.
Hello Dipo,
Please is there away to mark one correct and say given 50% scores?
Yes, you have to use Grading variables and a grading criterion. See https://moodleformulas.org/course/view.php?id=22§ion=22#tdm_20200320_2354 ↗.
Hello Robert,
What you propose, i.e. _relerr < 0.03*(_0==H)*0.5 + (_1==S)*0.5, is a boolean whose value can only be 0 or 1. You will therefore not be able to obtain a partial score with this formulas. What you need to do is check the two answers separately,
proceeding as follows:
Grading variables
score0 = abs(H - _0)/H <= 0.03;
score1 = abs(S - _1)/S <= 0.03;
Grading criterion
0.5*score0 + 0.5*score1
Hello Dipo,
Simply check the two answers separately. Proceed as follows:
Grading variables
score0 = _0 == 5;
score1 = _1 == 10;
Grading criterion
0.5*score0 + 0.5*score1
Hello Dipo,
(I am using a0 and a1 as the target answers.) There are 6 conditions to check, which you can define as grading variables:
c0 = 1.0*(_0 == a0 && _1 == a1); c1 = 1.0*(_0 == a1 && _1 == a0); c2 = 0.5*(_0 == a0 && _1 != a1); c3 = 0.5*(_0 == a1 && _1 != a0); c4 = 0.5*(_0 != a0 && _1 == a1); c5 = 0.5*(_0 != a1 && _1 == a0);
The grading criterion is then simply:
c0 + c1+ c2 + c3 + c4 + c5
