Profile with Design Section

Profile with Design Section

Introduction

Quantitative descriptive testing and sensory profiling are powerful tools for understanding the sensory characteristics of products.
Through structured evaluations, sensory attributes are evaluated by panellists, each assigned an intensity value. This process, often sequenced according to the order of perception, provides a comprehensive understanding of a product's sensory profile. 
Depending on the purpose of the test, panelists may focus on a single attribute category or evaluate multiple dimensions.
Within EyeQuestion, you can select a template that includes one or more design sections. Choose the number of design sections based on how many attribute categories you wish to ask. When the questionnaire has more than one design section, the questions will be repeated for all of the products in each design section before moving on to the next design section.
E.g. If a design section focuses on appearance, panelists will evaluate this section across all products before moving on to other sections, such as odor. 


Template Description

The template starts with a welcome screen that can be used for welcoming panellists, providing instructions, or asking additional questions prior to the test. Depending on the chosen template, the amount of design differs from 1 design section up to 9 design sections.
Each design section includes a screen with a single-line scale question type. You are free to adjust the line scale question type settings by clicking on the question type directly or add more questions/screens.

If a template with more than one design section has been selected, between each design section, there is a break screen containing a small instruction for the panellists and a waiting time. Both the instructions and the waiting time can be adjusted to your liking. To adjust the instruction, hover directly over the instruction question type. The waiting setting can be adjusted by clicking on the Screen Settings button and then selecting Waiting Settings.

In the end screen, the template incorporates a “thank you” message, providing an opportunity for you to personalize a final message for the panelists.

Within the design settings, you can see that the template is created with a monadic design. This means the panellists will receive and evaluate each product separately within each design. The individual design sections do not have a separate design and cannot be adjusted separately. When you would like to make a change in the design, this will be applicable for each design section. Within this template, there are two products included. You have the flexibility to adjust this amount in the design generator and edit the product properties by clicking on the Product section.

Raw Data Representation

The raw data will be displayed with each row corresponding to a product evaluated by a judge (panellist), followed by the rating of that specific product. In the sequence number column, the number equals the design that the panellist has answered the question. 

Analysis

Once data has been gathered, you can access EyeOpenR and navigate to the Sensory or Consumer methods. 
Suggested analysis for this specific template are:  
  1. Comparison values
  2. Table of means
  3. Bar chart 
  4. Line chart
  5. Spider plot
  6. T-test
  7. ANOVA with multiple comparisons tests
  8. Correlations
  9. PCA
  10. Product Characterization
  11. MFA
