Calculate a score

[Ahamada]

Hello comunity,

I have a table that looks like the table below. In this table we have questions (N1, N2, N3 and N4) of which N1 has 3 questions, N2 one question, N3 one question and N4 2 questions.
The answers are noted as follows:
a good answer to a question:
N1 is worth 0.33 (correct answers to the 3 questions N1 are worth 1).
N2 is 1
N3 is 1
N4 is worth 0.5 (correct answers to the 2 questions N4 are worth 1).

I would like to calculate the score by using the method below:

1. If all three criteria of N1 OK, score=1. If only one OK, score=0.33. If only two OK, score=0,66. (despite results of higher levels criteria -L2,L3 and L4)

2. If score=1, take into account criteria N2, if OK, score=2, if not score=1. (despite results of higher levels criteria -L3 and L4)

3. If score = 2 take into account criteria N3, if OK, score =3, if not score =2. (despite results of higher levels criteria -L4)

4. If score=3, take into account criteria N4, if both OK, score =4, if only one OK, score 3.5, if both KO, score 3.

id2	xxx	xxxx	xxxx	N2	OK
id2	xxx	xxxx	xxxx	N3	OK
id2	xxx	xxxx	xxxx	N4	OK

id3	xxx	xxxx	xxxx	N1	OK
id3	xxx	xxxx	xxxx	N1	OK
id3	xxx	xxxx	xxxx	N1	OK
id3	xxx	xxxx	xxxx	N2	KO
id3	xxx	xxxx	xxxx	N3	OK
id3	xxx	xxxx	xxxx	N4	OK
id3	xxx	xxxx	xxxx	N4	OK

Hi @Ahamada

that classic group by and count on the Answer field,
do something like:

Load Id_answer, Qestion, count(Answer) as NumAnswer

group by Id_answer, Qestion;

and then that will be a lot easier...

Hi @MendyS ,

I don't understand what "Count(answer)" will help us in this case.
could you explain your reasoning?
