Computing the final mark
The calculation of the final mark is processed in the following way:
Indicating with i the question number i, we define:
- n = number of questions
- minMark = minimum mark
- maxMark = maximum mark
- pi = weight of question number i; a number between 1 and 99
- fi = valuation of question number i; a real number between 0 and 1, so
computed:
* questions with multiple answer (or multiple choice)
(of right or wrong type):
fi=0 or fi=1
* questions with answer true or false, or
gap filling exercises, or
questions with matching words
guess sentences/words
fi = -------------------------------------
total number of guess sentences/words
- S = p1 + p2 + ... + pn ; weight sum
- F = p1*f1 + p2*f2 + .... + pn*fn
the final mark is computed as:
F * (maxMark
- minMark)
mark = minMark + --------------------------
S
Mark rounding rule
If mark round is different from 1, the final mark is rounded to the nearest mark
fraction.
Here some examples:
Round 1 / 2 = (0.5)
In a range from 0 to 10, the marks are:
0; 0.5; 1; 1.5; 2; 2.5; 3; 3.5 ..... 9; 9.5; 10
The rule is:
· If the decimal part of a mark is less then 0.25, the mark will be rounded to
lower integer;
· if the decimal part of a mark is between 0.25 and 0.75, it will be rounded to
0.5;
· if the decimal part of a mark is more than 0.75, it will be rounded to upper
integer.
Round 1 / 4 = (0.25)
In a range from 0 to 10, the marks are:
0; 0.25; 0.5; 0.75; 1; 1.25; 1.5; 1.75; 2; 2.25; 2.5; 2.75; 3; 3.25; 3.5 ..... 9; 9.25;
9.5; 9.75; 10
The rule is:
· If the decimal part of a mark is less then 0.125, the mark will be rounded to
lower integer;
· if the decimal part of a mark is between 0.125 and 0.375, it will be rounded
to 0.25;
· if the decimal part of a mark is between 0.375 e 0.625, it will be rounded to
0.5;
· if the decimal part of a mark is between 0.625 e 0.875, it will be rounded to
0.75;
· if the decimal part of a mark is more than 0.875, it will be rounded to upper
integer.
