# Making Sense of Multivariate Data using XLSTAT, BORDEAUX, May 20 - 21, 2020

This course covers the excellent features in XLSTAT for investigating, visualising and modelling data sets with measurements on many variables.

#### Making Sense of Multivariate Data

Depending on the application your focus may be on the objects measured (customers, products, physical samples etc. ) or the inter relationships between the variables themselves. There are multivariate techniques available to suit both these aims. Mathematical details are kept to a minimum and we focus on the interpretation of the outputs from XLSTAT and illustrate applications with case studies using data from consumer tests, instrumental analysis, manufacturing processes and biological data. We aim to explain the objectives of the techniques and to send you away with a better understanding of which technique to use when. There is plenty of opportunity for practice using XLSTAT through “hands on exercises” for which annotated solutions are provided and delegates are welcome to bring their own datasets to try the techniques.
