Prerequisites
Material: Basic Elements of statistics: descriptive statistics, elements of probability, statistical distributions, inference in normal populations (tests and confidence intervals for one and two means or variances) , ANOVA 1, simple and multiple regression .
Courses : LBIR1203 and LBIR1304 : Probability and Statistics 1 and 2
Main themes
1 . Statistics for measurement methods: reminders of Metrology (error types, quantification of error uncertainty, error propagation' ), variance components estimation by ANOVA, control charts, simple linear calibration.
2 . Experimental design in product and process development: Methodology , multiple regression and multiple response optimization , factorial designs and derivatives, screening designs, response surface designs , mixture designs and  optimal designs
3 . Multivariate statistical methods in chemistry: principal component analysis , partial least squares (PLS) , clustering, discriminant analysis and its application to multivariate calibration in analytical chemistry
4 . Applications with the JMP software
Aims
 At the end of this learning unit, the student is able to : 1 Contribution à l'activité du référentiel 1.1, 1.2, 1.4, 2.1, 2.2, 2.3, 3.4, 3.5, 3.6   At the end of the course students will be able to : -        Explain the interest of statistical tools in the work of the chemical engineer -        Explain the purpose and usage of each statistical tool seen in the course. select the one adapted to a given situation and calculate related parameters. -        Demonstrate their understanding of main course concepts by solving methodological exercises -        Use JMP software to apply the methods presented in the course. -        Interpret the results of a statistical analysis in the context of a case study in chemistry or life science. For specific tools -        Use statistical tools to quantify the precision of a measurement method -        Organise an experiment with the design of experiment methodology from the design selection to the statistical analysis -        Summarize / visualize large data sets (eg from spectral analytical methods) using multivariate statistical tools
