Ideal Profile Method
The Ideal Profile Method is a research and analysis technique used in sensory evaluation and market research to understand consumer preferences for products. It involves gathering data from consumers who are asked to evaluate products based on both their perceived and ideal intensities across a list of attributes.
Consumers are presented with a list of attributes related to a product (e.g., taste, texture, color) and are asked to rate their perception of the product on each attribute. In addition to rating the perceived intensities, consumers are also asked to provide ratings for their ideal intensities on the same attributes. This represents the consumers' ideal preferences for each attribute.
Consumers typically provide an overall liking rating for the product, giving a holistic measure of their satisfaction.
Build a survey for Ideal Profile Method
When building your questionnaire, go within the Design Section, click "Add Screen" and then "Add Question" within your screen.
When clicking Add Question you can select a Line Scale question type in the General Question folder. The scale has a range of 100 points, with anchors at 10 and 90 labelled as "Weak" and "Strong," respectively. You have the option to modify the default settings for this question type in the Standard Settings.
To use the Ideal Profile Method, ask two questions for each attribute: first, about how consumer perceive the product's attribute, and then about the ideal intensity for that attribute in the evaluated product category. Repeat this process for each attribute.
Each question type that is associated with an attribute can be named with that attribute name, while the ideal question type can be named "Ideal + Name of the attribute".
Make sure that the ideal and actual intensity attributes are kept together when developing the questionnaire. As a result, be careful not to request all real intensity attributes after requesting all ideal intensity variables.
You need to maintain the same sequence of ideal-actual or actual-ideal throughout the entire inquiry.
It should be either:
- Ideal Sweetness
- Intensity Sweetness
- Ideal Bitterness
- Intensity Bitterness
Or:
- Intensity Sweetness
- Ideal Sweetness
- Intensity Bitterness
- Ideal Bitterness
Different From Ideal
After data has been collected, you can run a Different from Ideal Analysis on the data collected using EyeOpenR.
To do so, open EyeOpenR from your project with the data collected and select "Consumer Methods".
Within the Analysis settings select "Different from Ideal".
Depending on the order used in the questionnaire, you can select the correct analysis option prior the analysis.
