Hello guys,

I need a clue:

I have an activity of two list of words. The first list, is the list of answers and the second list is the list of student list.

1) example

The student has a text and it must pick up all the verb from the text, then imagine something like this result:

student list       : 15 words

the student forgot to collect 5 words to complete all the list, what was its point in percent? How to calculate that?

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

2) Example

The student has a text and it must pick up all the verb from the text, then imagine something like this result:

student list       : 27 words

from 27 words, only 17 is correct all the remain words is wrong

what was its point in percent? How to calculate that?

thanks
Alexandre

I am also unclear about your question, but I will take a stab.

>> List of answers: 20 words
>>  student list       : 15 words

If 20 words are the complete set of correct answers, then if the student got all 20 words (instead of 15), his score would be:
(20 words from student) / (20 words from correct list) * 100% = (20/20) * 100% = 100%.

If the 15 words are correct (i.e., they match the answer list), but missed 5 words (or, equivalently, provided the 5 words, but got them wrong), then his score would be:
(15 words from student) / (20 words from correct list) * 100% = (15/20) * 100% = 75%

(Note: There are other grading systems where putting down a wrong answer results in more points taken off than just leaving an answer blank, but, for now, I assume that a wrong answer and a blank answer takes away the same number of points.)

There are many ways of calculating the grade but perhaps the best, applicable to all possibilities, is to calculate as follows.
Define A = number of words in the student list which are not in the answer list
B = number of words in the answer list which are not in the student list
AW = number of words in the answer list
W = 100(A + B)/AW    In addition set W = 100  if the previous calculation gives W > 100
Grade (in %) = 100 - W
