Question Type: Tetrad
Overview
Tetrad test is a discrimination test type that helps you determine if there is a difference between two products by asking panelists to group 4 samples into 2 groups of 2.
Unlike most other question types, the Tetrad question is not available as an option to add in a test. Instead, our pre-set Tetrad test type template is available to you to use in a click of a button, with the Tetrad question already included in it!
If during the test update you accidentally delete the question, don't worry. It will become available in the list of questions to add back into your test.
When you create a new Tetrad test, there are various options available in the Tetrad question to help you meet your data collection and analysis needs. In this workflow you will learn about these options and how to apply them.
Name Your Question
The Tetrad question included in the Tetrad test type template has the following default name: Add question name.
The purpose of such name is to prompt you to enter something more descriptive. If you do not enter anything differently, this default question name will be visible in your reports, and it might be visible to your panelists, depending on the Question options selected. We recommend that you update the Tetrad question name with more descriptive text.

Tell Panelists at the End How They Performed
For training purposes, you can enable the feedback feature to tell panelists whether they grouped the samples correctly. It is not recommended to provide feedback in real sample testing.
The steps below will guide you in providing feedback at the end of your test. This means that if there are Time delays, or follow up Comment, or follow up Choose questions in your test, the feedback will be displayed to the panelists after the time delays and follow up questions. If there are no time delays and follow up questions, the feedback will be displayed immediately after the Tetrad question.
If you are training your panelists, this setup is recommended. It will eliminate a possibility that the feedback will influence panelist response to the follow up questions.

- Select End of cycle.
- Review the Correct feedback text and Incorrect feedback text. Make any changes as necessary.
