Overview

The number of samples and their blinding codes play an important role in your Triangle test setup. You may create a single Triangle or a double (back to back) Triangle . In both Triangle types, there can be only one Triangle question in the questionnaire (the back to back part is handled by the Samples & design ).

In the workflow on this page we will focus on steps specific to single Triangle tests . Please visit the workflows listed below for other scenarios:

1. Back to back Triangle workflow (coming soon)
   
2. General Samples & Design workflow
   

Please go into the Samples & design tab of your single Triangle test and follow the steps of this workflow.

Add Sample Sets, Samples, and Design

1. In the Sample sets  field, type the number of sample sets required in the test. 
   
   
2. In the Samples field, type 2. When you click out of this field, the update will save.
   
   
3.  When the number of samples is saved, the design for a single Triangle gets automatically assigned. You can click View design to see what it looks like, and you can click Edit design if you wish to change it.
   
   
   The Edit design screen has the optional Shuffle sample set order feature. Choose whether you wish to shuffle the sample sets within the base design (recommended option if  you wish to use the shuffling feature) or across entire design. Shuffling sample sets is useful when you are using the same panelists for testing, e.g. employees, to eliminate a possibility that they might learn the sample order after a period of time.
   
   
   
   
   If you were editing the design, click Save . Two samples with default information will be listed.If you selected one of the shuffling options, you will have the Shuffle and save button instead. To verify what the shuffled order is like, click View design , or go to the Logistics tab and run the Serve reports .
   

Edit Sample Information

1. Type the new Blinding codes . Triangle tests require that each sample has two blinding codes because one of the samples is seen twice in each triad.
   
   
2. Type the Sample name for each sample. This information will be visible in the analysis reports, and if desired it can be made visible to panelists by using Wildcards .
   
   
3. Use the Column picker to display additional fields to fill them out, if desired.
   
   
4. Click Save .
