In short. Every shared quiz gets a results dashboard on Pro and higher with the number of participants, average and median score, pass rate, a score spread chart, the hardest questions and a question analysis with the share of correct answers, a discrimination index, point biserial correlation, median time per question and the most chosen wrong answer. Results download as CSV and as PDF answer sheets. On Elite they also go to your learning record store as xAPI, to a webhook and to the API.

What the results dashboard shows for every quiz

One page per shared quiz, updated as people finish. Here are the exact figures and columns.

Summary, score spread and participants

  • •Summary. Participants, average score, median score and pass rate against your pass mark.
  • •Score spread. A bar chart of scores in five bands, from 0 to 19 percent up to 80 to 100 percent.
  • •Participants. Name, email, score, Passed or Failed, finish time and integrity flags for tab switches and pasted text.
  • •Score adjustment. Correct a score by hand, the original score stays visible next to it.

The whole table downloads as CSV, and every attempt still has its own PDF answer sheet with the key marked.

Question analysis, one row per question

  • •Correct. The share of participants who answered the question correctly.
  • •Separation and time. The discrimination index compares the top and bottom 27 percent, and point biserial correlation relates each question to the total score, from 10 finished attempts. Median time per question appears from 3 answers.
  • •Most chosen wrong answer. The distractor that pulled the most people, with its share.
  • •Flags. Too easy, too difficult, possibly ambiguous, or does not separate strong and weak participants.

Flags appear from 5 answers, so a single early attempt never labels a question.

Who uses the quiz analytics and how

Teachers and trainers

  • •See who finished, who passed and who needs a second attempt, without opening every answer sheet.
  • •Find the concept that did not land from the hardest questions and the most chosen wrong answer.
  • •Duplicate the quiz, fix or replace the flagged questions in the copy and share it with the next group.
  • •Download the CSV for your records or your own spreadsheet.

Training teams and programs

  • •Send every finished quiz to the learning record store you already report from.
  • •Trigger Zapier, Make or n8n workflows from the signed webhook.
  • •Pull results into your own system through the API.
  • •Use the discrimination index to keep only questions that separate people who know the material.

PDFQuiz turns a document into good questions quickly, and the results dashboard tells you which of those questions did their job.

How the question analysis works

Item analysis rests on two numbers per question. The first is the share of participants who answered correctly. Questions that 90 percent or more got right, or 25 percent or fewer, tell you little about the group, because nearly everyone or nearly nobody got them, so PDFQuiz flags them as too easy or too difficult.

The second is how well a question separates strong and weak participants. PDFQuiz ranks finished attempts by score and compares the top 27 percent with the bottom 27 percent. You want the index positive: the people who did best overall should be the people who got this question right. Below 0.2 the question is flagged, and a negative index usually means the answer key or the wording needs a look.

When one wrong answer draws 35 percent or more of the people who answered, the question is flagged as possibly ambiguous. Read that option next to the correct one, the overlap is usually visible straight away.

What to do with the flags

  • 1.Start with questions flagged as not separating strong and weak participants. That is often a keying error.
  • 2.Rewrite possibly ambiguous questions so the most chosen wrong answer is clearly wrong.
  • 3.Replace questions that are too easy with harder ones generated from the same document at the advanced level.
  • 4.Duplicate the quiz and edit the copy. The original keeps its questions, so the results you already have stay comparable.

Quiz analytics questions people ask

What analytics does PDFQuiz provide?
Every quiz you share has a results dashboard on the Pro plan. It shows how many people finished, the average and median score, the pass rate against your pass mark, the score spread, the hardest questions, a question analysis table and one row per participant with their score, Passed or Failed and integrity flags. You can also download the invitee results PDF, a per taker answer sheet PDF and a CSV of all results.
Does PDFQuiz have an analytics dashboard with charts?
Yes. The results dashboard shows the score spread as a bar chart in five bands, the summary figures above it and the question analysis below it. Learners on Plus and higher also get a progress page with accuracy by question type, difficulty and topic and a weekly accuracy trend across all their quizzes.
Can I see how many people got a specific question wrong?
Yes. The question analysis lists every question with the share of correct answers, and the hardest questions list shows how many of the people who answered got it wrong, for example 7 of 20. Questions that 90 percent or more answered correctly are flagged as too easy, and questions at 25 percent or less as too difficult.
Does PDFQuiz calculate item discrimination or point biserial correlations?
PDFQuiz calculates the upper and lower group discrimination index, the share of correct answers among the top 27 percent of participants minus the share among the bottom 27 percent. It also calculates the point biserial correlation of each question with the total score. Both appear in the question analysis on Pro and higher from 10 finished attempts, provided there is enough variation to calculate the correlation. A question with a discrimination index below 0.2 is flagged for weak discrimination unless it is already flagged as too easy.
Can I export quiz scores to CSV or Excel?
Yes. The results dashboard has a CSV download with name, email, score, Passed or Failed, finish time, integrity flags and the original score when you adjusted it. The file opens in Excel, Numbers and Google Sheets. On Elite the same results are also available through the API and webhooks.
Can I track a student's progress across several quizzes?
A learner sees their own progress across every quiz they took on the progress page, with accuracy by question type, difficulty and topic, time spent per topic, a weekly trend and a list of what to study next. For a whole class, the Elite plan sends every finished quiz to your learning record store as an xAPI statement, so the history builds up in the platform you already use.
Does PDFQuiz connect to my LMS gradebook?
There is no LTI app, single sign on or roster sync. On Elite, results leave PDFQuiz automatically in three ways: xAPI 1.0.3 statements to any learning record store, a signed webhook after each finished quiz that Zapier, Make and n8n accept, and an API with a personal token. Quizzes are shared as a link.
How do I see results for a quiz I shared?
Open your quiz list and click the chart icon next to the quiz, or Results dashboard in its settings. The dashboard shows the summary, the question analysis and every participant. From there you can download the CSV and the invitee results PDF, or open a single attempt and download that person's answer sheet. You can also switch off the score display if you do not want takers to see their own result immediately.
What is item analysis, and should I be doing it?
Item analysis checks whether each question earned its place on a test, usually with two numbers: the percentage of participants who answered it correctly, and how well the question separates strong and weak participants. PDFQuiz shows both for every question and flags the ones worth a second look, together with the wrong answer chosen most often.
Which quiz settings affect what results you get?
Four of them. The pass mark decides who is marked Passed or Failed. Show score decides whether the taker sees their own percentage at the end. Random questions shuffles the order of the questions, though never the order of the answer options. Repeat attempts decides whether one invitee may take the quiz more than once, which changes how you should read a score list.
