Abstract
An exercise on the application of chemometrics for data interpretation, appropriate for a quantitative analysis course, is presented. Standard chemometric techniques such as principal component analysis and cluster analysis were applied to a multivariate data set of 14 river sediments samples containing ten heavy metals. The exercise was carried out by the students of a quantitative analysis class. The exercise allowed the students to develop the basic skills regarding how to extract meaningful information from experimental data.
Supplement
Metal concentrations of each sample, definitions, and a guide to Q-PARVUS are available.
