1. d' (read d prime): The measure of the extent of the overlap of panelist perception. It is the distance between the means of the two distributions measured in terms of their standard deviation.
   
   The larger the d’ value, the samples are more different. Where the d' value is 0 it means that the samples are indistinguishable. A d’ of 1 or less might be considered small and a d’ of 2 or more might be considered large, but it depends on various factors.
   
   This calculation is always done treating each response as independent, as if the test is unreplicated. For example, d' on a back-to-back test with 50 assessors who provide 2 responses, calculation is done as if there are 100 assessors who provide 1 response each.

Discrimination Analysis

Difference Test

1. Chance : The probability of panelists correctly selecting the odd sample by chance.
   
   
2. N : The number of evaluations included in the report. This will include Complete and Partial Results.

Additional Triangle Analysis

If your test included a follow up Triangle related Comment or a Triangle related Choose question, your Standard report will provide you with Triangle related Comments or Triangle related Choose data, depending on what question type you added into your test. Let's review what each follow up question provides in the Standard report.

Triangle Related Comments

If your Triangle test includes a Triangle related comment question, panelists' comments will appear in one of two tables; Correct response related comments or Incorrect response related comments.

Graphs

The data from a single and back to back Triangle can also be graphed. To generate the graph:

1. In the Results area, click the Graphs tab.
   
   
2. In the left sliding pane, select the Triangle question.
   
   
3. Update any of the parameters needed in the right sliding pane. Don't forget to scroll down to see all the different settings on the right.
   
   
4. Export the graph, or take a screenshot to include it in your reports.

PowerPoint Report

Generate a built in PowerPoint Report on your Triangle data to get a visual representation of the panelists' responses, and the statistical conclusion.

If you would like to generate PowerPoint Reports with your corporate branding in them, please contact our Support Team and they will assist you with the next steps.

Data

You can use the Data tab within your test, in the Results area, for a quick and easy insight into panelist performance within a single test (rather than across multiple tests as described below). The example screenshot above was taken in a single Triangle test.

Panelist Performance Report

Run a Panelist Performance report in the Panelists library to see how your panelists have performed over multiple Triangle tests over time, allowing you to discover patterns or non-differentiators. The workflow for the report will be available soon
