Statistical Analysis of Environmental Data

Learn how to use usual statistical methods for the description and interpretation of the environmental data.

Objective

Environmental data analysis, whatever the considered support, usually involves a statistical treatment of the available measurements. The course will help you better know and apply standard statistical methodologies to achieve relevant data interpretation of the data and help the decision-making process.

Key features

To better understand the theoretical concepts, half session is allocated to real case analysis and pratical exercises using Isatis and Excel.

Who should attend

This operational training is aimed at managers and engineers in the Environment industry who wish to understand and apply the usual statistics methods.

Course content
