The Uncertainty in Physical Measurements : An Introduction to Data Analysis in the Physics Laboratory The book targets scientists and researchers focused on experimentation in the fields of physics chemistry and engineering as well as graduate level students studying these sciences in an applied way. The central point is the uncertainty in measurements: what are the causes of uncertainty and how do we deal with it The possible causes of uncertainty are at first phenomenologically explored leading to understand the necessity of a formal treatment based on probability theory and statistical tools. The basics of probability and statistics are then introduced in order to support the most rele
