Product testing is part and parcel of any company’s new product development process. In fact, no new product or service gets commercialized unless the test is done and the new product has been shown to be favorably different than its competitor or perhaps significantly preferred or accepted by the test’s chosen set of respondents. As critical as it is though, product testing response data is either not fully or correctly taken advantage off. This could happen in various ways but the two most common are – (1) running the analysis primarily through descriptive summary statistics (e,g, averages) or graphical depiction of results which can highly limit the insight that can be gained or worse lead off to a wrong one; (2) applying the wrong statistical analysis approach (e.g. using the popular T-test to rank or rated data) which can give an erroneous conclusion.
Truth is, the proper statistical analysis approach to a product test or response data will differ depending on what measure is being used and studied as well as the number of treatments involved. Treatments could refer to alternative formulations, brands, designs, etc. Not only that, but also of important consideration is how the test was carried out such as independent or dependent (paired) testing of treatments, monadic or sequential monadic application, complete or incomplete treatment set respondent assessment. Taking into account these considerations, the statistical techniques to be covered will deal with the cases as follows:
  • Testing and analyzing difference between treatments (independent or paired) with objective measured data
  • Testing and analyzing difference between treatments (independent or paired) with subjective measure or sensory (rating/ranking) data with sensory fatigue considerations (incomplete treatment assessments)
  • Testing and analyzing preference between treatments (e.g. triangle or duo-trio tests) or acceptance of a treatment
This learning session will primarily be delivered through lecture considering the technical nature of the topics involved. It will follow a cycle of lecture then computational workshop for each statistical analysis tool and if time allows- a management of learning in the sense of how each participant foresees the potential application of the tools learned to their work or projects.

  • Develop the ability to identify and use the proper statistical inferential analysis tool contingent on the product testing design and project/study intent.
  • Correctly analyze, interpret and draw insights from product and design testing results.
  • Structure product and sensory evaluation test aligned to the development project/study intent and not be constrained by a limited set of statistical analysis tool to use.
