Interpreting the results of a STATIS analysis Select axes 1 and 2 as well as axes 1 and 3 and click the Done button. In the Charts tab, uncheck the Display charts on the first two axes box.Ī new box appears to allow you to choose the axes for which the graphs should be displayed. Moreover, since all the variables are on the same scale within each configuration, it is not necessary to reduce the variables. In the Options tab, check Global scaling in order to prevent any scaling effect. There are 6 subjects here that correspond to the 6 configurations.Īs the 6 configurations all have a different number of variables, you need to select a column containing the number of variables per configuration.Ĭheck the Object labels option and select the column containing the product labels (in our case the perfumes). In the General tab, select the Configurations (a configuration corresponds to the set of descriptors chosen to evaluate the products for a subject).Įnter the number of configurations. Select the advanced features / Sensory data analysis / STATIS. Setting up a STATIS analysis for Free Choice Profiling with XLSTAT The goal of this tutorial is to study and visualize the proximities between perfumes as well as to determine the agreements between the subjects. Each of the 6 subjects of the experiment have been asked to describe several perfumes by giving them scores for multiple descriptors that they had to choose by themselves. The dataset used to illustrate this Free Choice Profiling analysis can be found in the library SensoMineR in R. This tutorial will show you how to run and interpret a Free Choice Profiling analysis in Excel using the XLSTAT statistical software.
