Shannon Hickey May 9, 2011 10:45 PM (in response to phillysailor)One of the ways you can get more use out of choice columns is by assigning numerical values to choices. Consider the following question:
To assign numerical values, switch to the response view, select the Question, and switch to the type bar. Select "Choices" and "Edit Choice List":
Check the "Assign data values to choices". To support what you wanted to do, I gave the right answer 1 and the wrong answers 0:
Now you can perform calculations, and the data values that you specified are used in the formulas. You wanted percentage answered correctly. So try adding a summary row with formula:
And to finalize it, switch the type of this cell to percentage:
And there you go! :)
As you can imagine, you can extend this concept to do things like scoring entire tests. For example, say you have 10 choice questions. You give the right answer for each question 1 and the wrong answer 0. Now add an additional column that sums the question columns and you get your score out of 10 for each submission.
You also mentioned multiplechoice questions and grading. Doing that might be a little different. Can you give me an example and I'll think about how you might go about grading it?
Thanks,

Your answer is elegant, and I understand it. Nice, clear description, and I appreciated the screen shots.
It works if I want to test how the group answered each question.
But, I'd also like to grade each individual's test; in other words, how do I add a "summary column?" Is there a way to automate such a column (or quickly replicate such a formula for each row) so that it calculates the test score of each new submission?
The formula may require ignoring some cells, because some of the data entry by each person is for name, dates and other such "nongraded" responses.

3. You CAN "grade" responses!
phillysailor May 12, 2011 5:28 PM (in response to phillysailor)Ok, I figured it out
I just typed into the first available cell in the row beyond the first respondent's answers"=SUM(b1,c1,d1)/3" and instantly got my answer repeated down the whole column.
Slick. Like it knew what I wanted.

Shannon Hickey May 13, 2011 9:34 AM (in response to phillysailor)Hi Phil,
You're very welcome! That's how I'd go about grading individual responses also. One trick that might be helpful if you have a lot of questions (and they're sequential) is to use a range in your SUM expression. For example:
Then you don't have to explicitly mention each column in the expression.
All the best!
