Description

Objectives

This course is intended to provide basic and practical knowledge of statistics for those involved in managing, analysing and presenting quantitative information. Its intent is to cover, using a simplified but rigorous approach, the lack of knowledge that usually those that have not attended proper academic training during university but require to manage, analyse and present quantitative information.
During the course, some statistical tools will be used to show how to translate into immediate practical application the concepts presented.

Participants

CFOs, R&D, financial analysts, and anyone who needs to analyse measures and KPIs.
