Statistics are taken for curiosity's sake and for improving the test. Records of old trials are kept for the sake of measuring progress.
Here are the statistics on the current trial of the Triadic Enneagram Test. These statistics are on people who have reported their type while taking the test. They are divided into four groups, based on how certain people claim to be about their type.
If you haven't yet taken the test, please finish it before viewing the current statistics. These will reveal what each question is measuring for, which may influence how you answer the questions.
General Accuracy is the percentage of questions people answered according to the answers intended for their reported type. Pure chance should have a general accuracy of 33.33%. Bullseye Accuracy is the percentage of people who scored as their reported type. Pure chance should have a bullseye accuracy of 11.11%. Since these measures could be contaminated by the preponderance of one type over another, the Weighted measures avoid this kind of contamination by counting all types equally. No matter how many members of any type answer questions, all members of that type count equally with all members of any other type. Because of this, the weighted measures of accuracy should be regarded as the most accurate.

Beginning with trial #15, data is taken on how certain each person can be about what his/her type is. This data is used to break the statistics into four reports. Each report is on everyone who reported their type with at least a specified minimum degree of certainty. The first report is on everyone, and the other reports are on smaller and smaller samples.

Toward the end of trial 16, I updated the statistics page to reveal information on which set of triads each question is a best match for measuring. It is based on how many types have their top scores in the answers that fit a pattern for a particular triad. This information is useful for extracting useful information from questions that were a bad fit for what they were measuring. It can be used to find a better fit for a bad question, as well as to get ideas for new questions. In replacing some of the questions from trial 16 for trial 17, I eliminated questions whose best match was not what was being measured. This was different than my usual method of focusing on accuracy percentages, and it resulted in a slightly different selection of questions to replace. This resulted in dislodging some questions that had remained for a relatively long time. I also used best fit information from bad questions to write some of the new questions.
