I was looking for how to find individual question statistics on a quiz that uses random question selection from several categories. Searching the documentation was useless (while I use 3.5.3, it did not matter what version documentation I looked at).
Searching the forums was significantly more helpful. Using the search parameter "Statistics on questions from a question bank." Sixty percent of the first page results were what I was looking for. This tells me the documentation is woefully lacking. I know the search is supposed to do just that, but usually I get results from many more forum categories and the subject is usually more variable.
On the upside, Tim Hunt in a few posts on the topic sent people to MDL-48092. This gave me the key to finding the individual question statistics. In the hopes of being helpful, I have decided to summarize what I found and subsequently discovered.
The below images are from one of my quizzes.
|As you can see, question 9, 10, and 11 all draw from the same category (FLD-08 6Wi). Since there are 10 or fewer questions in that category, All questions are listed under question 11.
Clicking on a question provides that question statistics as described in the documentation plus it also indicates what position(s) that question appeared in on the quiz (see image below).
The above is fairly straight forward, however, what if there are more than 10 questions in the category?
In the image to the right, questions 12 through 15 originate from a different category than questions 9 through 11. This time, however, the questions are not listed below question 15. Instead, below question 15 shows general statistics for the category.
So how do we see the individual question statistics now? One suggestion in the forums is to download the statistics and analyze them with a spreadsheet like Excel. But that is cumbersome, slower than the alternative, and duplicates what is natively available in Moodle's statistics. It does work though.
Clicking on one of the questions listed, only shows the statistics for that question--so that is not the answer. The solution is in the last question in the category--in this case question 15--and click on that question link (Random (FLD-08 SmartTech)).
Below is only a partial image of the results of clicking on 15. This particular category has almost 30 questions. The statistics now show the same information as if the question category had 10 or fewer questions.
As you can see, the information also includes how many times that question was used.
Now clicking on the desired question number provides all the statistics the documentation discusses for questions.
In this particular exam I draw from seven different categories, some with less than 11 questions and some with more than 10. By using the instructions above I can now look at the statistics for every question.
I do have a question however, how do we get this information into the documentation?
I hope this has proven helpful and someday something like it will make it into the documentation.
