What the Moodle quiz report tells you

Teachers often open Moodle quiz reports after an exam to see how the class performed and which questions caused trouble. The Overview report lists each attempt with its grade and timing, while the Responses report shows the answer each student gave to every question.

Overview shows grades and timing for each attempt.
Responses shows each student's answer to every question.
Facility index near 0 or 1 flags questions that were too hard or too easy.
Negative discrimination suggests a question needs rewording or a corrected answer key.

Example Moodle quiz report questions

Which Moodle quiz report shows the actual answer each student selected for every question?The Responses report. It lists the response for each attempt, which the Overview report does not show.

In the Statistics report, what does the facility index measure?The average mark on a question as a share of its maximum mark. Values near 1 mean most students answered correctly, and values near 0 mean few did.

What does a negative discrimination index suggest about a question?The question may be miskeyed or ambiguous. Students with higher overall scores answered it correctly less often than students with lower scores.

Which report gives a row for each attempt with its grade, start time and state?The Overview report. It summarizes the whole quiz at the attempt level, so you can spot incomplete or overdue attempts.

What do the mean, standard deviation and Cronbach's alpha in the quiz statistics describe?The average score, how spread out the scores are, and the internal consistency of the questions. A higher alpha suggests the questions measure the same underlying skill.

Practice or export

Study in the browser on the Free plan, or export to PDF, DOCX or Moodle XML on a paid plan.

The Statistics report goes further. Its facility index shows the share of available marks students earned on a question, so a value near 0 means very few got it right. The discrimination index shows whether stronger students answered a question correctly more often than weaker ones. A low or negative value usually means the wording is unclear or the marked answer is wrong.

DeckOwl does not read attempt data from your Moodle site. What it does is create the questions themselves from your course material, with explanations, so you can write a fresh quiz, review the wording before it goes live, and then export it as Moodle XML on the Pro plan.

Frequently asked questions

What is the difference between the Overview and Responses reports in Moodle?

The Overview report summarizes each attempt with grades and timing for the whole quiz. The Responses report shows the specific answer each student gave to every question.

What does a low facility index tell me about a question?

A low facility index means only a small share of students earned the marks for that question. Check whether the content was taught clearly or whether the question wording is confusing.

Does DeckOwl pull results from my Moodle course?

No. DeckOwl creates quiz questions from the files you upload, and it does not connect to your Moodle gradebook or attempt data.

Is exporting to Moodle XML free?

No. Moodle XML export is included in the Pro plan at $14.99 per month, and the Free plan allows studying in the browser only.
