Learning objectives
Students will be able to deal with different challenges related to planning of experiments, quantitative analysis, quality control and comparison of data set
Prerequisites
Previous knowlwdge of analytical chemistry is requested, especially for solution preparation. The professor will give on demand a supplementary literature for students who will feel the need to fill any gaps.
Course unit content
The course will provide student with knowledge of theoretical principles and applications to food analysis of chemometric techniques as distribution, hypothesis testing, ANOVA, regression and experimental design
